Abstract

A high performance servomotor drive system is described for a salient pole PM motor in which an armature current vector is actively controlled according to load conditions in order to use a reluctance torque effectively, and as a result a large torque can be produced. The control algorithm of the armature current vector is described taking the demagnetization of permanent magnet and the magnetic saturation into account. Characteristics such as torque, power factor, efficiency, power capability, transient response, and so on are examined using computer simulations and experimental results.<>
