Unipolar Fixed-current Chopper – 4 Phase Stepper Motor Driver System
چکیده انگلیسی

This paper presents unipolar fixed – current chopper- 4 phase stepping motor driver, are remarkable for simplicity, high – reliability, multifunctional facilities for four phases hybrid stepper motor. The unipolar stepper motor controller/driver are designed which uses dedicated hybrid IC (HIC) which uses a MOSFET power device. The dedicated IC has the features of the SLA 7024 M or STK 6713BMK3, plus a simultaneous input prevention circuit that protects the IC from any malfunction the excitation signal. Self-excitation design means chopping frequency is determined by motor R and L. Support chopping at 20 kHz or higher, very low number of external components required. Excitation sequence signal is active low, and TTL level for direct interfacing to the microcomputer and gate array.
