This paper deals with the shape optimization of spoke type BLAC motor, in order to reduce cogging torque. This paper examines 3 steps skewing rotor angle, optimizing rotor core edge and rotor overlap length for reducing cogging torque in spoke type BLAC motor. The methods were applied to existing machine designs and their performance was calculated using finite- element analysis (FEA). Prototypes of the machine designs were constructed and experimental results obtained. It is shown that the FEA predicted the cogging torque to be nearly reduce using those methods.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {9}, number = {7}, year = {2015}, pages = {1280 - 1285}, ee = {https://publications.waset.org/pdf/10002013}, url = {https://publications.waset.org/vol/103}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 103, 2015}, }
