Torque Ripple Reduction of SynRM Using Machaon Type Lamination

2018    Kafadar, Ahmet Suat; Tap, Alper; Ergene, Lale T.

Synchronous Reluctance Motors are becoming more popular due to their high performance characteristics. However, the most prominent problem of these motors is the torque ripple. There are a lot of studies in the literature to reduce the torque ripple of this type of motors. Machaon type rotor stands out as a good solution. This study presents the effects of Machaon rotor with different rotor layouts, having different d&q axis insulation ratios, on the average torque and torque ripple of a 2.2 kW SynRM. Firstly, different d&q axis insulation ratios and rotor slot pitch angles are applied to a classic rotor structure and results are presented. Most promising insulation ratios and rotor slot pitch angle combinations are then selected and combined into a single lamination, creating a Machaon rotor. The results are compared with the reference machine and classic rotor types on the basis of average torque and torque ripple.
