Abstract :
To improve the stepping motor torque-frequency characteristic, a kind of double voltage driving circuit with feedback control for stepping motor was designed and discussed. The paper describes the construction, principle and some parameters´ calculation. The loading capacity of 3 kinds driving circuits has been compared with each other by experiments. Double voltage driving circuit with feedback control can improve driving capacity of circuit at high frequency, and eliminates high frequency electromagnetic noise during chopping process and over heat of chop transistor in constant current chopping circuit.
