Abstract:

In this paper, two types of switched reluctance motors (SRMs) with segmental rotors are presented in detail. One is 6/5 segmental rotor type; the other is 12/8 segmental rotor type. Both these two types of motors have the same stator, rotor and winding configurations. The stator is constructed with special stator poles in which the exciting and auxiliary poles are designed exclusively. The rotor is constructed from a series of discrete segments, each of which is embedded in the nonmagnetic isolator. The windings are only wound on the exciting poles, and no windings are wound on the auxiliary poles. With these configurations, short flux paths and high flux-linkage utilization rate in the proposed motors are achieved, which may reduce the magneto-motive force (MMF) requirement and increase the electrical utilization of the machine. To verify the proposed two motors, the characteristics of the proposed two types, such as magnetic flux distribution, flux-linkage, torque, torque ripple, radial force and efficiency, are analyzed and compared with that of conventional 12/8 SRM. Meanwhile, the two prototypes, one for each proposed segmental rotor type, are also designed and manufactured. Finally, the validity of the proposed two motors is further verified by the test results.
