Torque Optimization Control of Dual-Gap Dual-Pole Composite Machine for High Efficiency and High Dynamic Performance

In order to achieve high efficiency for double stator motor system, this paper proposes an efficiency optimization control method based on the minimum copper consumption function. This method calculates the load ratio of the internal and external motors when the output efficiency of the double motor system is the highest, which realizes the reasonable distribution of the system torque output. The simulation model of the dual stator motor system is established to verify the effectiveness of the method.
