  • Page 23 11.4- EQUALIZATION. Equalization changes the phase current profile in the medium speed range. If equalization is excluded, current profile reference approximates sinusoidal shape independently of speed. If equalization is active, current profile reference is switched to a square shape when speed exceeds a certain threshold: as a consequence, with equalization active, the torque output of the motor will be increased in the medium speed range.

  • Page 29 5. In case of short circuit or failure of power device transistor, the motor could make an uncontrolled movement within a range up to 180 degrees in electrical angle (180 degrees in electrical angle=1/50 of a turn) and then remain a stable position. It is necessary to verify that this limited movement does not correspond to some risky conditions.
