It is reported that the city of Kun Ming has been doing a research on whether should limit the speed of electric bikes or not. It is also said that they are considering limiting the speed under 15km/h. As we all know that with the development of e bike kits, their speed is getting faster and faster. Most of them even have the same speed as the motorcycles. And so they lead hundreds of traffic accidents as well as being called the "Road Killers". However, when doing this research, there are many citizens thinking that it is ridiculous. They thought if they should limit the speed of their e-bike under 15km/h, then what's the reason they bought e-bikes rather than the normal bikes. So the research slowed down the pace of limiting the speed of e bike.

In the past few years, electric bikes are always considering as environment friendly, convenience, helpful. In a word, their effects on people are almost those positive ones. However, in recent years, e-bikes have become one of the most painful headaches of those traffic policemen. Why? You may ask for the reason. The reason is that e-bike, now, has become the "Road Killer". Yes, they are the killers on the road. Since now, the traffic accidents that caused by the e-bikes have reached to one third of the total traffic accidents' number. Why do e-bikes become the road killers? It was reported that there are the following main reasons. Firstly, the ignoring of the small problems of e bike kits. Secondly, the e bike drivers' disobey of the traffic rulers. All of these need us attention to decrease the traffic accidents.

Electric bikes are made for the idea to protect the environment by decreasing the discharge of exhausts. And now they are popularized so well. Not only for the environment protection, but also because of the lightness and conveniences, e-bike has already become the most popular vehicle. However, when people are enjoying the benefits brought by the e-bike, they are also suffering the all kinds of dangers coming along the e-bike. In recent years, the traffic accidents that caused by the e bikes are becoming more and more. And their number has even surpassed one third of the total traffic accidents. Why are e-bike traffic accidents so many? It turns out that the main reason is the disobedience of e-bike drivers. And also some e bike drivers do not turn on the lights to save the power. What's more, because of the better of e bike motor, some drivers drive too fast.

We became instant friends. Every day for the next three months we would leave class together, I was always listening to this "time machine" as she shared her wisdom and experience with me.
It was heard that Professor Green in our college had written a love letter to her, but she refused. Professor Green lost his wife three years ago, he was gentle and humorous, and all of us like to attend his class. He usually guided us to visit the brushless motor factory at weekends, every year he introduced many students to work in the large outrunner brushless motor company, as he was an expert in the field of brushless motor design, the entrepreneurs are glad to hire the students he introduced. "Why did you refuse Professor Green? He is really a nice man." I asked Rose after hearing of the news.
I was busy with the PPT demonstration on the brushless motor of electric cars these days. The PPT demonstration will be looked as a final test to our credit earning. It is one of the most important major courses, so all of us tried our best to make it a perfect ending.
My demonstration was made up of four parts: basic structure of brushless motors, basic principles of brushless motors, testing standards and methods used, Analysis of the specific brushless motor controller case of the column. I had been willing to do such a research all the time; it is the chance that gives me the opportunity to share my acquired knowledge with my classmates and teachers.
The demonstration will be hold next week, there were only four days left, I have just finished a small part of it. I decided to spend this weekend finishing it.
Stepper motor's output torque is decreasing with the increasing of the speed, and it would drop dramatically when the speeds is higher, so its maximum operating speed is generally at 300 ~ 600RPM. AC servo motor has constant torque output, which can output rated torque in its rated speed (typically 2000RPM or 3000RPM). Above the rated speed, it is constant power output.
Generally, stepper motors do not have overload capacity. However, ac servo motor has a strong overload. Take Sanyo AC servo system for example, It has the speed and torque overload abilities, its maximum torque is two to three times bigger than the rated torque .which can be used to overcome the inertia of the load moment of inertia at the start moment. Because there is no such overload for Stepper motor, you need to overcome this moment of inertia in the selection of induction motors.

As a kind of open-loop control system, stepper motor is intrinsically linked with modern digital control technology. In the current domestic digital control system, stepper motor is widely used. With the appearance of all-digital AC servo systems, AC servo motor also are increasingly used in digital control systems. In order to meet the development trend of digital control, motion control systems mostly use digital stepper motors or AC servo motor as the implementation of the motor. Although the both are similar in the control (pulse train and direction signal), there are big differences in applications performance and occasions.
AC servo system is superior to stepper motor in many performances. But stepper motors are used as the implementation motor in some less demanding situations. Therefore, control requirements ,costs and many other factors must be take into account in the control system design process.
Stepper motor's control is open loop control; it is easy to emerge the phenomenon of stall and lose the load step when the start frequency is too high or the loaded is too bigger. Therefore, to ensure the accuracy of the control, you should solve the handle up and spin-down problem well. AC servo drive system is closed loop control, the motor driver can directly sampled the motor encoder feedback signal, Internal structure compose of the position loop and speed loop, so it generally does not appear lost step or stepper motor overshoot phenomenon, the control performance is more reliable. The speed response performance between stepper and servo motor also are different, Stepper motor needs 200 ~ 400 ms accelerates from zero to operating speed (typically several hundred per minute, rpm). AC servo system has better acceleration performance.

Stepper motor is an open loop servo motion system actuator, it uses the pulse to control and send off the angular displacement. Compared with AC servo motor and DC servo motor, the outstanding advantages of stepper motor is low cost, moreover, it without any accumulation errors. However, the stepper motor has many deficiencies in operation aspect, such as low-frequency oscillation, noise, low distinguish rate etc. these defects have severely restricted the application scope of stepper motor. The running performance of stepper motor has close relationship with motor driver. The shortcomings of the stepper motor can be overcome by the improvements of drive technology.
Relative to the other drive, subdivided drive methods not only can reduce the step angle and improve the resolution shelter of stepper motor, but also can reduce or eliminate low-frequency vibration and make the motor run more smoothly. In summary, the effect control of sub-driven is the best.

Hot summer coming, the fan has become one of the summer heat products again. Currently, there are many other tricks in technology, functional areas of fans on the market negative ions, ultra-quiet, double blades, five blades, and other functions photo catalyst endless is dazzling. In fact, the fan structure is relatively simple, the most critical and most easily damaged and also the most valuable thing is the motor. Certainly, motors used in fans mostly are brush motor, but there are also some high-end fans use brushless motors. Motor is the core component of the fan; good fan motor can stimulate the fan and long-term operation without damage, and poor brush motors is easy to break down. Motor is the basis of fan quality. A good motor make the overall operation of the fan is quieter and more comfortable.
Servo motors have a wide range of applications military, industrial and daily life. With the ripe of computer technology and the development of field technology, it also contributed to the servo system implementations and architecture continues to evolve. Control constituter’s digital control servo system has attracted more and more attention. Fieldbus-based Distributed servo system has many advantages, such as less connection, high reliability, easy system maintenance and expansion and so on. Currently, foreign corporations Siemens, ORM EC Systems, Rexroth and other companies already have launched their own product distributed servo motor controller system; Some domestic scholars also has sponsored the research of this units, but the relevant papers is countable, and there is Nor a series of products.

On June 27th, 2010, the Izip Store promoted the future opening of their first electric bicycle store which will open this August, in Venice, California. There were over 300 LA city lovers riding their bikes 18.5 miles through different downtown neighborhoods and landmarks, from historic, folkloric, and urban to modern. Passing City Hall, Cathedral of Our Lady of the Angels, Pueblo, Staples Center, the 3rd street tunnel, the Fashion District, Wholesale District, Grand Hope Park, the 4th and 6th street bridges, LA Live, and other remarkable downtown locations. It was a very well organized, enjoyable way to explore the city. The Izip Store donated an Izip Via Lento electric bike to this wonderful and green event to help motivate citizens to park their cars and experience riding their bikes as an alternative: to school, work, grocery shopping, gym, park, library, etc., and encouraging people to stop using gas powered bicycle, especially for these types of short distance trips (usually 3 to 4 miles).

Electric bike manufacturers are convinced that Americans will turn to e-bikes that can be pedaled like a bike or ridden like a scooter. They've been around for a while, but the third-generation e-bikes arriving in bike shops feature relatively lightweight frames and fast-charge, removable batteries. They're easy to ride, a cinch to store and dirt cheap to run. Dozens of e-bike manufacturers attended Interbike for the first time, and Schwinn was there promising to have the $3,2300 Tailwind e-bike it developed with Toshiba in showrooms next year. Schwinn claims the battery's good for 25 miles and can be recharged in as little as seven minutes using a commercial charger. Schwinn's confident there's a big market for e-bikes. "Electric bikes are a dramatically growing phenomenon within the U.S., and we intend to be a serious contender within the e-bike category," Schwinn executive Bruno Maier said in a statement.
In most electric bikes, you can see a kind of very important engine --- brushless direct current motors (bldc motors). BLDC motor is of the motor types rapidly gaining popularity. BLDC motor is a type of synchronous motor. This means both of the magnetic fields generated by the stator and rotate are at the same frequency. The BLDC motor is featured in longer life (because no more brushes are needed), high stating torque, high no load speed and smaller energy losses. BLDC motor comes in single-phase, two-phase and three-phase configurations. Three-phase motor is the most popular and widely used in e-bike application. The structure of the BLDC motor is divided into two parts: the moving part, which is called the rotor, represented by the permanent magnet; and the fixed part, which is called the stator, represented by the phase windings of the magnetic circuit.

Recently, more and more people choose to by electric vehicles. But do you know the exact of these vehicles? Maybe most of us only know they are made for the environmental purpose. Let me introduce the details of them. Electric bikes (e-bike) include two-wheel bikes propelled by human pedaling supplemented by electrical power from a storage battery (bicycle-style), and low-speed scooters propelled almost solely by electricity (scooter style). The main components of e-bike include a hub motor, controller and value-regulated lead-acid (VRLA) battery. Bicycle-style e-bike typically has 36V batteries and 180-250W motors. Scooter-style e-bikes typically have larger 48V batteries and high-powered motors (350-500W). Electric bikes are regulated not to exceed 20km/hr, but many, especially scooters, can travel at speeds in excess of that limit and some are advertised to go 40km/hr. Now, have you known more about electric vehicles?

Do you want to maximize the riding range of your electric bikes? Now do with me. Firstly, you should fully charge the battery before a long journey. Rough road conditions and hilly terrain will consume more energy. Frequent change of speed will consume more energy. And also, carrying more weight on the e-bike will consume more energy. Keeping the tires properly inflated and keeping the e-bike clean and well lubricated will save energy. Making sure that both wheels move freely when brakes are not applied will save energy. You should check brake adjustments frequently. And also the e bike motor should be checked more frequently. Pedaling as you ride will consume less electrical energy and increase the riding range. When the battery is turned off, your e-bike functions as a regular bicycle. By doing so, your e-bike can not only be ridden longer, but also have longer riding range.

Battery belongs to one of the most important electric bike bits. Your e-bike battery must be a lithium ion battery. Lithium ion battery requires specially designed chargers. So you should never charge your battery with a substitute charger that is not designed for this use. Use of an unsuitable charger to charge a lithium ion battery will result in over-heating, fire or even explosion. If your charger is lost or damaged, contact your dealer to order a replacement. Charge your battery while the e-bike is not in use. You should turn off the battery before you charge it. The length of charging time depends on the level of charge the battery still holds. If a battery is completely discharged, it will take 4 hours to be fully recharged. When a battery is fully charged, the LED on the charger will transition from RED to GREEN. There are still a lot that need us attention when we use electric bike.

I had gotten married and lived with my husband for fifteen years and our marriage had experienced many traverses and was hard-won, so I thought we should cherish it and days we lived together. My husband was a talkative man and was good at coaxing women, so I was afraid he still kept in touch with his old lovers. He stayed in his brushless dc motors all day long and went home late very late during that period of time. I called his and he said every time that he was accompanying his customers having dinner. I rode my electric bicycle and went to the restaurant he frequented, but I could not find him. I realized that there was something wrong with him, but I had no evidence. I could not figure out why he cheated me and did not tell me about the truth. I stopped my electric car at the door of a dc electric motors factory, because I could not nearly move at the thought of my husband's cheating me. I would not live if he really betrayed me, because I loved him so much.
I suddenly felt that love was so strange that I could not understand it at all. I thought loving a person was to do everything I could do for him, no matter how much the costs were and what kind of the counterpart was. I knew clearly that there would be no result between us, I still fell in love with him crazily and was out of control. I worked in a brushless rc car motors factory and was always absent-minded during the working time at the thought of him. I could not understand myself sometimes. I knew that it was me who would be injured in the end, but I still loved him and missed him every day. I rode my electric bicycle after work and went to his working place to have a look at him quietly without his knowing. I would be very content if I could meet him and his face. This was love and I did not know how to express it. I would get off the motorized bicycle and stood far away from him and stared at him carefully. It was enough for me being able to gaze at him in a far distance.
