MOTOR CONTROL SYSTEM AND METHOD WITH ADAPTIVE CURRENT PROFILE

摘要

Subject to user or system selection, one of the motor control schemes is accessed from the memory (56) by a controller (44) for implementation. The controller (44) generates control signals that are applied to energization circuitry (42) for supplying current to the phase windings (38) with a particular current waveform profile in accordance with the selected motor control scheme. The controller (44) has an input terminal (47) for receiving a user initiated torque command signal representing a desired motor torque. Each motor control scheme provides motor driving current that corresponds to torque command signals received at the controller input terminal.
