This paper presents an innovative electronic magnetic geared (EMG) motor. The motor is designed and tested. This electronic EMG motor assembles parallel, serial or hybrid connections of stator windings into gears to accommodate the different speed and torque demands in the drive cycle. The objective of EMG is to increase the maximum speed and maximum torque range of the motor. A 1.5 kW prototype EMG motor was built up and tested on a test rig. The test results prove that the theory of EMG is correct. It will have a large positive impact on the energy efficiency of electric vehicles.
