Working Principle

MDM97294-3339 works according to the following principles: The system driver, usually a permanent magnet being used, is connected to the DC power supply. The voltage, current and feedback signals acquired are used to control the rotation speed of the motor. First, the system current is removed from the motor, and then the positional information is detected using Hall Effect sensors installed in the motor. Based on this information, the motor is started and the motor speed is restored. The voltage and current are then adjusted based on the speed feedback to maintain a constant speed.

As the speed increases, the current and voltage become too high, and the system control unit will automatically transmit the stop signal to the system. At this time, the motor will graduallystop, and the system current will be cut off to protect the motor from damage and overheat.
