Ripple Torque Synchronous Reluctance Motor with Different Rotor Designs

Abstract

The article is devoted to the study of ripple torque synchronous reluctance motor. In the research, simulation computer simulation methods were used. Investigations were carried out of the interconnected change in the amplitudes of the higher harmonics of torque for various designs of the rotor of the synchronous reluctance motor. These studies differ from previous ones in that the rotor configuration is considered in interaction with the motor stator. Moreover, to obtain reliable results, the magnetic flux generated by the stator windings remains unchanged in all studies. Four variants of the synchronous reluctance motor rotor are considered, which are currently most often used in motors of this type. This factor makes the results relevant for practical use. The article shows that the rotor, at which low pulsations of torque are obtained, allows to obtain high energy characteristics of the synchronous reluctance motor.
