How can we improve the efficiency of energy?

Posted by jiahaojin on May 31, 2011 at 3:17 AM Comments comments (0)

As China increasingly serious problem of energy shortage, in the practice improve the production of energy efficiency is the trend. However, most oil fields in western China is still exist a large number of associated gas venting phenomenon. Associated natural gas this can be treated by simple separation of direct-drive high-power gas engine, generator and drive into the power grid, thereby enhancing the comprehensive utilization of energy.

DSPÂ?s application in brushless motor

Posted by jiahaojin on May 31, 2011 at 3:15 AM Comments comments (0)

TI introduced the 240XDSP as a brushless DC motor digital control core, consisting of servo system requires very little system components. TMS320F240X is high-performance 16-bit digital signal processor (DSP) U.S.TI launched, which is designed for digital motors controls, The DSP includes a fixed-point DSP core and a series of micro-controller peripheral circuits, to put digital signal processing and computing capability for efficient control of the motor in one, it can replace analog devices in software to easily modify the control strategy revision control parameters, both for fault detection, self diagnostic and communication host computer functions.

Posted by jiahaojin on May 27, 2011 at 3:20 AM Comments comments (0)

China e-bike 2011 was held from April 27-30 2011, at the Shanghai New International Expo Centre. The event was organized by China Bicycle Association, jointly sponsored by Shanghai Xie Sheng Exhibition Co., Ltd and Shanghai International Exhibition Co., Ltd. That year's exhibition area was more than 100,000 square meters, an increase of more than 10% from the previous exhibition. Exhibition area for overseas vendors has increased by 10%. The exhibition was divided into more than 10 specialized exhibition zones, including bicycle and spare parts, electric bicycle and spare parts, motorcycle and spare parts, stroller and spare parts, machinery and equipment, bicycle travel leisure products, etc. It had attracted exhibitors from 1132 well-known enterprises from over 14 countries and regions such as Italy, Holland, Switzerland, France, Germany, the United States of America, India, Japan, Korea, Pakistan, Hong Kong and Taiwan. The event was held with the purpose to use electric bikes to protect our environment. So we hope the event will be held every year.

Adhering to the brand development philosophy of "honest management, high quality, best service" and embodied the aim of "technology initiate the future, excellence create the quality, service establish brand", we exert ourselves to promote the technological innovation, management innovation and service innovation, striving to be the most excellent electric bike motor controller supplier.

One Saturday

Posted by jiahaojin on May 27, 2011 at 3:16 AM Comments comments (0)

When my husband got promoted in his factory, I asked him to take me to the factory and had a look at it one Saturday. He hesitated and did not want to take me along with him. I suddenly felt that he did not care about me before he got promoted. Maybe I was too sensitive. I saw that he was unhappy when I rose to go with him for the first time to the brushless electric motors factory, so I gave up the idea, because I was afraid that he would go angry and did not want to force him to do the thing that he did not want to do. I was also afraid of losing him. Our marriage was so hard-won and I would always try my best not to quarrel with him on a tiny matter. I rode my best e bike and went shopping on my own that day. I would be very content as long as my husband did not go angry with me and was happy and I would not bother him. After finished going shopping, I went to my friend’s motorized bicycles shop and chatted with her for several hours. We talked about men and women and our marriages.

My Husband and His Old Lover

When my husband could not find a suitable person to manage our new branch factory after my cousin came back from there, I proposed that I was pleasant to go there and replace him. He did not agree with the proposal at the beginning, but I was so firm that he had no way in the end. I found that I had forgotten my mobile phone when I was on the way to the brushless electric motors factory, so I went back to my husband’s office. His old lover was sitting and talking with him on the sofa when I arrived at the office. I was jealous and went out angrily after I got my cell phone. I thought that he would run after me at that moment, but he did not. My tears poured down when I saw her brushless ac motor electric car in the courtyard. As a matter of fact, I had lived separately with my husband for several months because of his old lover, who had become the barrier between us. Another friend riding her e electric bike saw me crying in my car at the roadside, she stopped the car and asked what the matter was.

My Friend and Her Husband

A friend of mine called me one night, saying that it had been several days that her husband had not returned home and asked me how she should do. I was an experienced person on that kind of matter and she had found the right person. I rode my hub motor electric car and went to her house after I hung her telephone. I advised her to go to his husband?s company and have a look at him; she said that she dared not to go at the dark night, so I accompanied her to go there. Her husband was not in the company when we arrived at there. We sat beside the electric bike waiting for him. My friend told me that she was afraid of being cheated by her husband and she would not live if he betrayed her. She said that she could not imagine if her husband had done something that was sorry to her. a person riding a micro brushless motor electric car told us that her husband was not in the company that day. He had told her that he was working overtime in the company when she called him, but he was not at all. Why he had cheated her.

Convert servo motor into continuous rotation

Posted by jiahaojin on May 24, 2011 at 3:06 AM Comments comments (0)
Any servo motor can be converted into variable speed motor. Generally speaking, you need a driver chip and other components if you want to control the motor speed and direction, and servo motors have equipped with these devices already. Modifying servo motor is the most common and cheapest; to get the transmission method of digital control used in the robot, thus to get a continuous rotation servo motor. The partly of this change is mechanical and electrical. The change section of electrical part is to change to potentiometer into two fixed resistors with resistance; the change section of mechanical is to remove the brush motor part of the full rotation of the stopper. Modified servo motor is complete in terms of performance.

The factors that affect the operation of dc brushless motor

Posted by jiahaojin on May 19, 2011 at 3:35 AM Comments comments (0)

Brushless DC motor is the abbreviation of Brushless DC execution servo motor; it is a type of synchronous motor, it is means that the rotor speed was effect by the speed of rotating magnetic field of stator and rotor poles (P): n = 60 * f / P . Under the circumstance of the fixed number of poles, the change of the frequency of the stator rotating magnetic field can change the speed of the rotor. Brushless DC motor is that synchronizes motor added to electronic control (drives, including the Ministry of Power and Control Division); Control the frequency of the stator rotating magnetic field and take the rotor speed feedback to the control center to correct repeated, so as to get close the way of DC motor’s characteristics. It means that among certain load, brushless motor can still control the motor rotor to maintain a certain speed when the load changes. Brushless DC micro-motor is one of them.

The earliest used motor in the world

Posted by jiahaojin on May 19, 2011 at 3:33 AM Comments comments (0)

The world’s earliest Prototype motor is permanent magnet electrical motor, but because the performance of permanent magnetic materials in that time was poor, so electromagnetic motors have been accounted for the mainstream. The birth of Alnico permanent magnet made the permanent magnet motor to start the advent of development, but because of its relatively high price, the application surface of Alnico magnet motor is not widespread. Since the emergence of low-cost ferrite, the application of permanent magnet motor substantially increases. According to statistics, among DC motor below 500W, the permanent magnet motor accounts for more than 92%, most of which is ferrite permanent magnet brush motor. The emergence of samarium cobalt permanent magnet makes high-performance servo motor to be achieved.
