It is reported that the city of Kun Ming has been doing a research on whether should limit the speed of electic bike 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, e-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 . 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 motor , testing standards and methods used, Analysis of the specific brushless motor controler 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.
