【Abstract】 Abstract-In this paper we introduce a design method of Rare Earth Permanent Magnet (REPM) Brushless DC Motor (BLDCM) controller with dual-redundancy which is used in the servo actuator , and the method is designed on the basis of a MCU. The hardware structure, software design and working principle of the controller are discussed in detail in the paper. Furthermore we also introduce the PWM speed regulating mode, the control of MCU, the logic signal synthesis and the practical application of current cut-off degenerative circuit. Through experiments we can make a conclusion that the controller has a high performance, a tight structure, a low cost, and also has a good reliability and practicability.更多还原
