A Swappable Single Phase Switched Reluctance Motor with Bifilar Drive Converter

摘要

Single phase switched reluctance motors (SRM) has special place in high volume, low-cost and low-performance applications as well as high-speed, low-power motor drives in different industrial applications. Single phase SRMs have some disadvantages such as low power density and lack of the self-starting ability. In order to overcome these problems a few methods have been presented. For example utilization of permanent magnet or special rotor configuration or additional mechanisms are some of this approaches. Have been adoped by different researchers Many of these methods are expensive or make the manufacturing process more difficult. This paper proposes a new method which overcomes these problems. The proposed approach focuses on a new single phase SR motor topology which will address a procedure for reliable starting, The single phase motor utilizing a new converter topology for this motor and the corresponding control methodology. The new configuration enables the motor for self-starting without the use of permanent magnet or any other starting device. The prototype was simulated, fabricated, and tested in laboratory. Simulation and experimental results of the proposed SRM drive system are presented.
