ABSTRACT:
An electronically commutated motor is controlled by controlling the winding current of the motor. During an operational mode change of the motor, the winding current is first changed to a value in excess of the value needed to maintain a measured motor parameter at a desired level. When the desired level of the parameter is reached the current is changed to the value needed to maintain the parameter at the desired level. In addition, the communication time of the motor is shifted such that the temporal maximum of the magnetic field of the motor coincides with the position of the motor poles which results in attainment of a maximum speed altering force.
