Permanent magnet (PM) synchronous motors fed by PWM inverters are widely used for industrial applications. The PM motors sometimes have a saliency, in which the q-axis inductance is larger than the d-axis inductance. This paper describes a high-performance servo drive system of 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 PM and the magnetic saturation into account. The several characteristics such as torque, power factor, efficiency, power capability, transient responses, and so on are examined in detail by the computer simulations and experimental results.
