Abstract :
It is required to calculate the electromagnetic forces at the distributed parts of electric machines for the prediction of performance. In this paper, the body force distribution of electric machines such as surface permanent magnet and interior permanent magnet is presented and discussed for the first time using the recently developed body force calculation methods which are based on the virtual air gap scheme. The torque contribution of the body force is investigated according to radial and circumferential directions
