4KW controller

Electric Vehicle’s Controller Product Specification
1. Product Descriptions

The product is the latest PMSM controllers made by our company, and the output power up to 2500W. The product uses the FOC(Field Oriented Control)algorithm in which SVPWM is used to drive the power device. Meanwhile, by using a 32-bit microprocessor which incorporates the latest ARM core,it exhibits excellent operational capability and task processing ability. The system handles several close loops which include torque, flux and speed loop and at the same time other high demand of real-time task operation is possible. By advanced control solution the system can achieve the following performance: maximum torque control, constant power control, speed closed loop control and energy feedback control while braking. Compared with traditional DC motor (BLDC) controller, the PMSM controller has the following obvious advantages:
Direct torque control,smooth start-up,excellent acceleration performance Vector control sinusoidal current injection and smooth motor output torque, which fully suppress the low frequency noise caused by the fluctuations of motor torque.
Provide PC software(GUI),by which hundreds of parameters can be configured, improve the flexibility of on-site application;
UART(standard )or CAN (optional)
Over-current protection, over or under voltage protection and over-temperature protection.
