Abstract
Embodiments of the invention provide a method of operating a motor connected to a power device having a reduced current rating. The motor can include an increased torque constant and/or an increased back electromagnetic force constant in order to decrease a peak current in relation to the reduced current rating of the power device. The method can include increasing a length of time the motor can operate at the peak current without overheating. A phase angle of the motor can be advanced in order to achieve a continuous operating point with the power device having the reduced current rating.
