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.
Claims4
A method for maximizing power output in a synchronous motor, said method comprising the steps of:
- generating a torque-producing current within said synchronous motor being optimal with respect to torque and power generation;
- deriving a field-generating current from said torque-producing current;
- deriving an optimal torque-producing current from said torque-producing current and said field-generating current;
- generating an optimal voltage corresponding to said optimal torque-producing current;
- and
- using said optimal voltage to control the power output in said synchronous motor.
