Integrated Magneto Drive Unit with Synchronous Reluctance Motor

The global transition toward electrified transportation and energy efficient industrial drives is intensifying the demand for electric machines. This paper proposes the design of a novel axially integrated magneto drive unit (IMDU) with synchronous reluctance motor. The structure and operating principle of the proposed machine is analyzed. Genetic optimization is used to globally optimize the design parameters of both the reluctance motor and the magnetic gear. Then the electromagnetic performance of the proposed IMDU is investigated using finite element analysis. Comparative studies between the proposed IMDU and conventional surface mounted permanent magnet machine has been conducted, and the results show that the average torque of the IMDU is 70.62% higher than surface permanent magnet machine with the same size, the same amount of magnet and the same current density.
