Study on Measures for Meliorating Driving Power Characteristic of Stepper Motor

To enhance torque and frequency characteristic of stepper motor and propose measures for improving meliorating driving power capability,experiments on single voltage,high-low voltage and frequency modulation voltage were carried out.By analyzing its operational characteristics,applying various methods to improve the driving power of stepper motor,improving front and back edge of current rising,thus maintain normal value of different phases in high-frequency and low-frequency so as to improve the motor's torque-frequency characteristics while in operation.
