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.
DC input control
DC is a technology that uses analog signals to control the circuit. It changes the motor speed by changing the input voltage amplitude. This is an older motor input control method.
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.
