Abstract
An apparatus (10) for controlling an electric motor (36) having a plurality of motor phases includes a motor controller (32) that controls energization of each phase of the plurality of motor phases. A compensation circuit (56, 84, 104) is associated with each phase of the plurality of motor phases. The compensation circuit (56, 84) of one phase of the plurality of motor phases adjusts a control parameter of another phase of the plurality of motor phases an amount functionally related to an electrical characteristic of the one phase in response to determining a diminished operating characteristic of the one phase.
