As the key part of battery powered DC motor driving system, the motor speed controller's performance decides, in a great scale, the whole system's performance.
Incorporating with the newly developed digital technology and semi-conductor / microprocessor technologies, motor controllers are now much more compact in size with fully tangible functions, for example that we may set almost all vehicle functions through a single controller, forward / reverse, speed regulation, reverse alarm, brake, temperature inhibit, etc.
Along with the development history of motor controllers, many companies step in and out the stage. The successful players become industrial giants, like CURTIS Instruments, ZAPI Group, SEVCON, etc.
As the largest single market of battery powered vehicles, China offers the opportunity for all motor controller developers and manufacturers. After 40 years' economic opening, some national controller brands grows rapidly, to be able to stand should by should with the international brands. Focusing on differentiated product areas, Chinese companies masters now the control technology of brush-less permanent magnet drive motor. A significant fact is that the annual production of over 30-million electric scooters of China is almost 100% equipped with controllers made by local manufacturers. While the major scooter makers use often their own motor control unit (assemblage integrated with throttle, lighting control, horn, brake, display and sometime the on-board entertainment platform), the professional controller developers provides variable solutions covering the full range of an electric scooter.
Surprisingly, you get very few quality complains in this huge electric scooter market. It is true that many scooter controllers are not good in quality if we go back to 10 years age. But here in China, the intense market competition has given serious lessons to the bad quality products. Imaging it, if you try to conquer a small city market (a really small city in China, maybe ranked between 200th and 250th largest city in dimension of population. In China, there are over 300 cities of population over 500,000.), the market capacity is 60,000 scooters. Then will you risk to lose the market share by providing the low quality product when there are other 20 or 30 competitors are vising to get into this market? The only solution of winner is to provide the products of the best price / performance ratio. So you can see, the market capacity is a key factor for Chinese market.
For international controller brands, like CURTIS and ZAPI (INMOTION), they moved in China, building their own factories and research facilities. But they are focusing on a different section of motor controller industry: large and medium-sized complex controllers with high technology threshold. These products serve for electric forklift, solar & wind power station, marine equipment, etc. Of cause, they tried also to enter economic controller market by providing products with simplified design and lower price, as well as their Chinese counterpart is trying to make some advanced technical products for the high-end market. For the moment, it is hard to say who will be the big winner. But one thing is certain, when the domestic market grows, Chinese buyers are seeking for better performance of their scooters, golf carts, electric cars and many other battery powered motor application.
