Anjana M P, Shinoy K S, Jeena Joy

The paper aims to design and develop a five phase permanent magnet BLDC for aerospace applications. A radial flux, surface mounted permanent magnet BLDC motor was designed with 33 slots and 10 poles and the analysis was carried out using finite element method in COMSOL Multiphysics. Hall sensors were used for getting the position of the rotor for proper energisation of the stator winding. The cogging torque obtained is less than 1% of the actual torque due to the fractional slot pitch windings which is verified by the simulation. According to the design a five phase motor was implemented and validated that the resistance and inductance value obtained during the analysis was found matching with the developed motor.
