A study of dual-channel brushless DC motor with permanent magnets

The paper discusses the concept of brushless DC motor with permanent magnets for a high-reliability drive. The possibility of improvement of vehicle drive reliability was shown on the example of a motor designated to drive of a small electric vehicle. The drive reliability can be improved by using two independent power converters which supply a motor with distributed windings in a double star connection. Results of motor studies in single-channel and dual-channel operation were presented. Conclusions concerning the analysed solution were formulated.
