Abstract
A start-up controller is programmed to reduce current to a motor during a coast phase of an alignment state of the motor. The alignment state is divided into a plurality of phases based on time elapsed from the start of the alignment phase and the controller reduces the current when the elapsed time is substantially between a start and end time that define the coast phase. Because reduced current is provided to the motor during the coast phase, the total power and thus the thermal load on control components for the motor is decreased while the time the motor requires to 'settle' into alignment is only slightly increased.
