Abstract
A method of adjusting motor control voltages for a permanent magnet rotor motor comprising three phase coils, each phase coil having two free ends, the three phase coils being without a common node. The method comprises driving the motor by applying motor control voltages in turn to respective pairs of the three phase coils with a remaining one of the three phase coils not being driven. Then, determining for each of the pairs of the three phase coils respective values of a motor operating parameter. The values of the motor operating parameter are compared and, based on said comparison, three-phase stationary reference frame motor control voltages v, v, vgenerated for driving the coils in a field-oriented control (FOC) mode of operation are adjusted to provide adjusted three-phase stationary reference frame motor control voltages v', v′, v′for driving the coils in the FOC mode of operation.
