Abstract  Stepping motor is the most popular executive component in high performance textilemachinery, especially in the computerised embroidery machine. Five-phase hybrid stepping motordrivers in the computerised embroidery machine have a good many defects such as low frequency torque vibrations, high frequency inadequate torque output and multi-power supplies. Combinedwith theoretical analysis, this paper gives a reformative driver based on analysis of present stepping motor drivers. This driver uses single power supply and three-phase excitation and givesPWM output. The design improves the stability in low frequency and the torque-frequency characteristic in high frequency and it has been applied in the computerised embroidery machine and has achieved a real good effect.

Key words： MCU      stepping motor      excitation ways      hardware circuit      software design
