PWM input control
PWM is an effective technology that uses digital signals to control analog circuits. By changing the pulse width, the speed of the motor is changed. At present, most automobile motors use this type of input control.
LIN input control
LIN is a serial communication network with strong noise immunity and high stability. By changing the communication data to change the speed of the motor, it can also realize the real-time communication between the on-board central control computer and the motor ECU to monitor the running status of the motor. This is a relatively new control method. To
Electronic water pump used in air-conditioning blower cooling fan
Power: 200 to 1000 watts stepless speed regulation overload protection, stall protection, short circuit protection, over temperature protection, high/low voltage protection, fault self-diagnosis and feedback. Compared with brush motors, brushless motors have longer service life , The noise is lower, the structure of the motor is simple, and the cost is lower.
