Permanent Magnet Synchronous Machines (PMSMs) are getting popular in the automotive applications which are necessary for high power density in low volumes. Also they have a huge usage potential in other industrial applications like robotics, naval applications, space applications etc. In this paper, design parameters of a special PMSM are analyzed which has two independent winding set for motor and generator operations in a simple stator instead of two separate electrical machine. Important design parameters like skew, airgap length, slot-pole combination, magnet height-width which affect the output performance are investigated for multi tasked PMSM. Performance output values are analyzed for two operation situation of multitasked PMSM and optimum design values are determined. These values are obtained from Maxwell-Simplorer softwares where co-simulation analysis has been run.
