ABSTRACT Synchronous Reluctance Motors (SRMs) are defined as reliable electric motors. Although the history of this type of motor dates back a very long time, their usage areas have started to increase with the developments in power electronics in recent years. While they have advantages such as their simple structure and their ability to operate at high speeds, the biggest disadvantages of these motors are the torque ripple (torque pulses) that occur at low speeds and the acoustic noise caused by this disturbance. One of the methods used to overcome this problem is the formation of a skew in the rotor structure. In this study, in addition to the traditional skewing method, a different degree of skew is created by creating a unique skew shape and compared with the normal motor topology. The analyses are carried out using Finite Element Method (FEM). The results obtained are given in detail.
