Description
Summary:Most of the automobile companies are in to the research and development of electric and hybrid vehicles to promote fuel efficient and environment friendly vehicles. Being one of the major energy consuming part in hybrid and electric vehicles, an electric motor should have high efficiency, high torque density in all the drive cycles and must be compact in design. This paper presents a structure for the permanent magnet electric motor which has both axial and radial magnets and a common electromagnetic core for both. This common core provides path for both axial and radial flux. This structure enhances the magnetic loading and hence developed torque and facilitates more air flow inside the motor. A comparison study on air gap flux and developed torque between motors having conventional core structure and proposed core are presented and these are validates with Finite Element analysis.
