Working Principle

The PM25CL1A120 Electronic Module works by receiving commands from the controller, which sends pulse-width modulation (PWM) signals to the module to control the speed of the motor. The module then translates the digital signals into three-phase output signals, which drive a three-phase motor. The power MOSFETs in the module act as switches that control the current running to the motor, based on the inputs from the controller.

The module is also capable of measuring the current running to the motor, using a current sense amplifier, and giving feedback control signals to the controller, allowing it to monitor the motor\'s performance and adjust the speed of the motor accordingly. Additionally, the module contains internal protection features, such as current limit protection, thermal shutdown, and overvoltage protection.
