摘要

An apparatus for controlling an electric motor having a controller, a torque demand limit generator, and a drive stage. The controller may be arranged to receive as an input a torque demand signal indicative of the amount of torque demanded from the motor and to produce as an output a set of motor current demand signals. The drive stage may receive the motor current demand signals and is arranged to cause currents to flow in each phase of the motor as required to meet the demanded torque. The torque demand limit generator may be arranged to output a torque demand limit signal indicative of a torque demand limit above which the battery current would exceed one or more limits.
