Analysis of Operation Modes and Control for a Multiple Torque Component Single Air Gap Magnetless Machine

The fault-tolerant capability of the electrical machine system in the event of certain faults is critical for application in the fields of aerospace, in-wheel vehicle, etc. This paper analyzes the operation modes and control principle of a novel type of machine with multiple electromagnetic torque components. Firstly, the topology and operation principle of the electrical machine are briefly illustrated, and then the mathematical model, and especially the torque component is introduced. After that the control principle considering the characteristics of multi-torque components is analyzed. Finally, the operation modes of the machine under different working conditions are analyzed.
