OLMNG


The rotor speed and position estimation is not reliable when the motor is running at low speeds. Hence,this information cannot be used to control the motor at start up and low speeds in sensor-less mode. Themotor needs to be started with a forced angle (open loop angle) instead of estimated angle.


Features and Benefits


  • Generates angle for open loop operation
  • Switches angle between open loop and closed loop based on closed loop status
  • Controls the motor direction in open loop
  • Operates in per unit, where 2^16 represents rated values
