Performance Analysis of Hub BLDC Motor Using Finite Element Analysis

This paper deals with the application of steel (M19) material and composite material in HUB BLDC motor to analyze performance of the motor. The motor must be designed in proper dimensions for particular application then only the motor can be used, if the design is not proper the motor will not able to rotate freely and it draws heavy current. Before manufacturing the motor, the torque should always be less than that of net torque. Four configurations of (a) steel (M19) material with stator and rotor and (b) composite material with stator and rotor (c) Laminated steel (M19) material for Stator and soft composite material (SMC) for Rotor and (d) soft composite material (SMC) for Stator and Laminated steel (M19) material for Rotor have been studied to obtain their nodal temperature distributions by using finite element analysis in different parts of stator and rotor frames. The study tells that the steel (M19) and Soft composite materials (SMC) based stator and rotor frame has a good thermal capability and it provides better feature in electrical vehicles. It mainly deals with the analysis of magnetic field, magnetic Flux distribution, and current density in the core.
