Currently there are many of the brushless motor manufacturers ; single manufacturer market share is generally low, the market concentration is not high. With the development of Chinese industrial economy, brushless motor, brush motor and other motor types are widely used. According to statistics, the motor system electricity consumption accounts for about 60% of the total consumption of the country, of which fan electricity consumption accounts for 10.4%, motor pumps account for 20.9% and compressors is 9.4%.However, the products efficiency of more than 80% domestic is2% -5% lower than foreign advanced level. Motor system efficiency is10% -20% lower than the foreign advanced level. Therefore, our country has a huge demand in improving efficiency and energy management system of motor system.

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 e-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 bicycles 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.

IFT5 series three-phase permanent magnet AC servo motor of Germany Siemens is divided into standard form and short forms two categories, a total of 98 species of 8 frame size specifications. It is said that t and compared with IHU series of DC servo motor output torque, the weighs of his series AC servo motor only is the half of the former, Matching transistor PWM drive 6SC61 series at most can supply 6-axis motor controls Germany Bosch Corporation has produced ferrite magnets SD series (17 standard) and rare earth permanent magnet SE series (8 specs) AC servo motor and drive motor controller Servodyn SM series. American well-known servo Production Company Gettys as a Motion Control Division of Gould Electronics once before, but it is producing M600 series A600 series AC servo motor and servo drives now. After the merger to the AEG, Gettys’ name was restored, the company introducted A700 all-digital AC servo system later.

There was dull pain at the bottom of my heart at the thought of his sad words one day. He was my only friend and I had a lot of words in front of him. He was an easy-going man and I could tell him everything to him. I gradually depended on him too much. When I asked him to buy me an electric bicycle , he bought it without hesitation; when I told him that I was lack of money, he gave me; he would try his best to do everything he could do for me. But one day, he changed completely. He said that I had been twenty eight years old and I should not have relied on him so much; I should find a reliable man and get married with him. I was in tears when I was working in the electric brushless motors factory. I could not believe he should have had said those words to me and my heart was broken. I had fallen in love with him so deeply and I could not extricate from it. My tears dropped on a small dc motor . I was more painful than losing relatives when I heard those words.

The situation would get better if I did not call him that day and our relationship would not be so stiff and I would not have regretted my behaviors so much. I wanted to meet him and kept on calling him time and time again when he did not answer my telephones. I thought that he had no reason not to answer my phones. I borrowed my neighbor’s motorized bicycle and went to his office to have a look and wanted to know what he was busy with. I got a shock when I arrived at the door of the office. He should have had been playing cards with a gang of young people. I left there with the electric bicycle sadly. I was not convinced and called him again; he answered and shouted me loudly, saying that why I was so disgusted and that I was the most disgusted girl he had seen. My tears poured down. I was injured deeply after I heard those sad words. I passed by a brushless motors factory and a worker at the gate stared at me when he saw my eyes were in tears.

Japanese Fanuc Company is famous for producing CNC equipments, but the company also introduced S series (13 specifications) and L series (5 specifications) permanent magnet AC servo motor in the mid-80s of 20th century.
