| Abstract: | This paper describes a full-digital control system in the flux-weakening mode with two microprocessors for a new surface-mounted permanent magnet synchronous motor, which has an additional reluctance rotor part. The reluctance part has a very high d-axis but low q-axis reactance. For flux-weakening, the d-axis armature current is adequately controlled with one of the microprocessors. The novel current control scheme and velocity regulator are presented. Experimental results show that the speed range of the new motor is expanded. |
