Study of Switched Reluctance Motor Directly Driven by Commercial Three-phase Power Supply

The conventional three-phase induction motors (IMs) have been widely used in various applications because three-phase IMs can be directly driven by commercial three-phase power supply, however, their efficiency are not high due to copper loss in the rotor. To overcome this problem, as an alternative for IMs, a novel three-phase Switched Reluctance Motor (SRM) which can be directly driven by commercial three-phase power supply without converter, inverter and some sensors is proposed. In this paper, it is shown that the proposed SRM can generate the continuous torque and can start by using the simple and low cost drive circuit consisted of only six diodes and no switching devices by the simulation.
