This chapter discusses magnetic‐geared (MG) motor drives, including their system configurations, magnetic gears, MG machines, power inverters, and control strategies. The MG motor drive essentially consists of the MG machine, power inverter, and electronic controller. Mechanical gears are well developed and utilized to a great extent in industrial applications that a couple of mechanical gears have been adopted as a symbol of modern industrial civilization. The MG machine can be considered as a machine integrated with a magnetic coaxial gear. The operating principle and mathematical modeling of the magnetic coaxial gear is the key to realize the desired performance, namely the high‐speed machine design and low‐speed output rotation. As the MG motor drive possesses the definite merit of gearing effect, the designs of two MG PM brushless motor drives for in‐wheel EV propulsion are used for exemplification.
