Brushless dc motor controller application is very extensive, such as cars, tools, industrial control, automation and aerospace and so on. In general, the brushless dc motor controller can be divided into the following three main purposes: 1, continuous load application: mainly needs certain speed but for speed accuracy is not high, such as the kind of applications such as fan, water pump, blower, lower cost and more this kind of application for the open loop control. 2, variable load application: mainly speed need to change within a certain range of application, speed and dynamic response time characteristic of motor controller has a higher demand. Such as home appliances in the dryer and compressor is a very good example of oil pump in the field of automotive industry control, electric controller, engine control, etc. , this kind of application system cost is relatively higher. 3, positioning applications: most of the industrial control and automatic control belong to the category of the application of this type of application tends to complete energy transmission, so the dynamic response of speed and torque have special requirements, taller also to the requirement of the controller. Speed may be used when the photoelectric and synchronous equipment. Process control and mechanical control, and transport control, many of them belong to this type of application. Brushless dc gear motor controller, small volume, light weight, high bearing capacity, long service life, stable running, low noise. Has the power split, alone with the features of tooth mesh. Maximum input power of up to 104 kw. Brushless dc gear motor controller is suitable for hoisting, transportation, engineering machinery, metallurgy, mining, oil chemical industry, construction machinery, light industry, textile, medical equipment, instruments and meters, automobiles, ships, weapons, and aerospace industries.
