摘要：

A number of transport vehicles have been fitted with electric traction motors and their inverters. The traction motor is required to continue to operate even if the inverter is under fault conditions. We propose a motor with two controllable rotors for a traction motor, which consists of two rotors and one stator. In this article, we propose a fault-tolerant control method for a two-controllable-rotor motor using a six-phase inverter. The operational principle of the two-controllable-rotor motor is described. The mathematical model under fault-tolerant control is shown, and a fault-tolerant control method for the two-controllable-rotor motor is described. The proposed fault-tolerant control method is verified by conducting finite element analysis (FEA) and carrying out measurements on a prototype.
