Flux switching, Maximum Torque, Output power, Iron loss


IIn today’s world, the Permanent Magnet Flux Switching Machine (PMFSM) has attracted researchers because of the high torque and power provided. In addition, the stator has both armature winding and PM excitation sources, and the salient pole rotor is relatively simple and strong. However, there is a major problem that occurs in the conventional rotor in the PMFSM such as a longer flux path, winding loss, and high iron loss. In addition, the conventional rotor has a higher weight which is not suitable for high-speed applications. Thus, this research introduced a new structure of the rotor called the modular rotor. The modular rotor has advantages that can reduce the mass of the motor and enables the reduction of iron losses. The performance of 6S-10P conventional PMFSM and 6S-10P, 6S-14P, and 12S-10P modular rotor PMFSM are analyzed at load and no-load conditions and the result for the maximum torque achieved, output power, and the weight of the PMFSM are observed. As a result, 6S- 10P conventional rotor design produced the highest maximum torque and output power among all the other designs with the value of 45.37 Nm and 10.77 kW. However, the total weight of conventional rotor PMFSM calculated is the heaviest which is 7.71 kg while 12S-10P modular rotor PMFSM has the lowest weight which is 6.42 kg.
