  • Closed-loop start without position sensor
  • Non-inductive FOC motor control algorithm, so that the motor noise is small
  • Can control a water pump and a drain valve
  • Input power overvoltage protection/under voltage protection/motor phase loss, short circuit protection
  • High-temperature frequency reduction work to protect the safe and reliable operation of the motor
