Abstract
Switched reluctance motor (SRM) is considered one of the most recent types of electric motors, which combines the performance of the dc series motors in a rigid brushless configuration. Most previous studies have been restricted to the conventional rotational SRM with two poles per phase. The present thesis introduces an analytical and experimental investigation for three different types of SRM namely, a four-pole per phase, an arch type, and a linear motor configuration.
A three-phase four poles per phase SRM has been designed and investigated to evaluate its performance in comparison with the conventional 6/4 three-phase type. A new configuration of three-phase arch SRM has been introduced, designed, and investigated to emulate the linear motor type. Once, a successful operation has been obtained, a full linear configuration has been designed, built and investigated. A design procedure has been developed for the linear motor type, based on the motor rating, to obtain the core dimensions and the electronic power converter specifications. An analytical study has been carried-out for different motor types, which included both the steady state and dynamics. The developed models consider both magnetic saturation and power electronic non-linearities. An experimental prototype system has been built for each motor type, which included the motor, the electronic power inverter, shaft encoder, and the interface circuits.
from the present study, it has been found that the proposed three-phase four poles per phase SRM type has higher torque capability and wider speed range than the conventional type. The arch type emulates the linear type especially in the steady-state operation where it becomes difficult to investigate the linear type on short run ways since steady state operation can not be accurately achieved with such cosnditions. The proposed linear SRM is characterized with its high thrust, which is essential for linear applications.
