 Frequency small step motor system is what works? Let toy motor for you. Analysis: Power supply: Power Inverter part because of different size and different output power DC motors, low-power multi-purpose single-phase 220V, three-phase 380V in the power of power. Because of the design capacity of the motor used in the middle, so the use of a three-phase 380V power supply. Rectifier circuit: AC rectifier into a pulsating DC motor production, must be filtered. In this design, three-phase uncontrolled rectifier. It can make the power factor close to 1. Current and voltage detection: general in the middle of the DC side signal acquisition, processing motor as overvoltage, undervoltage, overcurrent protection signal. Control circuit: The 8051 and SPWM wave generation chip SA4828, the main function of the control circuit is set to accept a variety of information and instructions, drive inverter operation signal formed in accordance with these instructions and setup information. These signals are optically isolated to drive after switching off the tube. Motor prices, Zhongshan motor, the motor is provided by Chang Xin Xin Motor Co., Ltd., Dongguan Chang.
