Design and Mathematical Modeling of Gearless SMC Flux Reversal Generator for Wind Turbine

摘要

This paper considers the design of the three-phase gearless flux reversal machine with magnets on the stator. Its magnetic core is made of soft magnetic composite material and is a solid of revolution with a slot for laying the winding in the middle. 48 magnetic poles are located on the surface of each stator tooth, the rotor has 24 teeth. This paper describes the mathematical model and the results of calculating the performance of the three-phase soft magnetic composite flux reversal machine operating in a generator mode. Comparison of the calculated characteristics of the considered machine with the characteristics of the generator with magnets on the rotor which cores are made of laminated steel is given. Gearless flux reversal machine can be used as a generator for a wind turbine.
