Four Phase Switched Reluctance Motor Direct Torque Control

Abstract

The three-phase switched reluctance motor direct torque control method mostly is a simple transplantation of the three-phase AC asynchronous motor direct torque control method, not suitable for arbitrary-phase switched reluctance motor. In this paper, the direct torque control method for the application of a wide range of four-phase switched reluctance motor will be researched, the structural methods of a four-phase switched reluctance motor flux vector and the choice principle of voltage vector are put forward, the direct torque control system for four-phase switched reluctance motor has been achieved. The results of the method and control rules are easy to extend to arbitrary-phase switched reluctance motor, the foundation of arbitrary-phase switched reluctance motor direct torque control will be established.
