Abstract
A method of maximizing the power or torque output of a synchronous motor with reluctance effect is disclosed. Bases on torque and voltage set points, in the regulation of the synchronous motor, an optimal torque- and field producing current is generated. The method can further generate an optimal voltage which can maximize the power output of a synchronous motor since changes of inductances generated by the current itself can be accounted for.
