Descrição: Toroidal stator permanent magnet brushless DC machines are novel, double-sided, axial-flux, disc type machines with high power to weight ratio and high efficiency. A TORUS motor works very much like a separately excited DC motor with very low armature reaction. To extend the TORUS motor into the electrical traction field, a method for wide speed range is proposed by weakening the flux created by the permanent magnets. According to this scheme, experiments and modelling of the motor are carried out. The results prove the assumption is feasible. The implementation of this project is carried out with an improved IGBT inverter using a Flight-68 K microprocessor as controller.
