Abstract

See full text

A method for controlling an electric motor includes inputting a quadrature-axis current (Iq) and a direct-axis current (Id) into an electric motor, receiving speed feedback indicative of the speed of the electric motor, determining whether the speed of the electric motor increases given the input Iq, and controlling the Id to increase the speed of the electric motor by selectively weakening the electromagnetic field if the speed of the electric motor does not increase given the input Iq.
