- Abstract
- This paper proposes a novel skewed-type iron slot wedge that can improve both thecogging torque and the output power of a permanent magnet synchronous generator (PMSG).
Generally the open slot structure is adopted in a PMSG due to its convenient winding work, but thehigh cogging torque is undesired. Firstly, an iron slot wedge was utilized to reduce the cogging torqueof an open slot type PMSG. However, the output power of the machine decreased rapidly with thismethod. Thus, a proposed skewed type iron slot wedge is presented to improve the output power aswell as the cogging torque as compared to the open slot type. Shape optimization of the skewed-typeiron slot wedge is performed to simultaneously maximize the output power and reduce the coggingtorque. The Kriging model based on the Halton sequence method and a genetic algorithm are used tooptimize the design.
