How to realize the high-speed DC brushless motor drive?

High-speed brushless motorhas a simple structure, low noise, free maintenance, no commutation spark, and can directly by the mains rectifier power, etc, in the constant speed drive devices, such as fan, water pump, elevator, automatic door, also can be used in the speed control driving device, such as logistics transportation equipment, packaging equipment, printing, food, and some precision equipment, such as: Cutting machine, CNC bed, medical equipment, can also be used in home appliances, such as air conditioning, refrigerators, washing machines, etc.

High-speed brushless motor

Micro high-speed brushless motor is the most widely used and close to our products, high-speed brushless DC motor can be used in electrical appliances, power tools, medical equipment, our mechanical and electrical high-speed brushless DC motor model many, parameters, performance and drive can be customized according to customer requirements. High-speed brushless motor components are stator, rotor, hall plate, front and rear end cover, among which the driver part is particularly important.

High-speed brushless motor driver is composed of the power module, digital signal controller DSC, intelligent power module IPM, high voltage DC brushless motor, position signal acquisition module, motor parameter acquisition module, protection module, braking module, user interface, and communication module, etc. According to the parameters required by the customer and the parameters set by other control systems or by the RS232 interface, the driver adjusts the driving signal of IPM by combining the rotor position signal and the current state of the motor to realize the control of the brushless motor.
