Starting control for an electromagnetic machine

摘要

A control for operating an electromagnetic machine in a starting mode of operation detects a magnitude of a parameter of power applied to an armature winding of the electromagnetic machine relative to a stationary frame of reference and converts the detected parameter magnitude into field and torque producing components relative to a rotating frame of reference. A power source coupled to the armature winding is controlled during operation in the starting mode such that a rotor of the machine is accelerated.
