A high performance electrical drive needs a smooth torque waveform and a high torque to inertia ratio. The power density and performance needs can be, in most cases, fulfilled by using a permanent magnet synchronous machine (PMSM). This paper explores a new cogging torque reduction technique. This method can be used without reducing the power density of the machine and it can also be applied in a mass production process.
