Our MR3 motor-protection filters protect against the problems arising from the use of high-power semiconductor elements and are installed between the variable-frequency drive (VFD) and the motor. The motor-protection filters are connected to the outputs of the PWM converters to prevent losses caused by motors’ starting current or overheating and to extend the life of the motors.
