Abstract
Stepping motor is an electrical machine which could be controlled accurately. Thanks to its fine functions, it has been popularized in the industrial production. With the rapid development of the computer digital controlled technology and the permanent magnetism materials, it has been opened a promising prospect for the application of the stepping motor. Therefore it’s very meaningful to study the stepping motor controlled system.
High-performance stepping motor control system has been developed. Single-chip microcomputer is used as the CPU, SPGT62C19B is chosen as the drive of the stepping motor, so the expensive exclusive controller for the stepping motor could be omitted. two_phase four_beat stepping motor is controlled by the single-chip microcomputer AT89C51. The working principle of the system, the hardware circuit and some software program are demonstrated, the safety, reliability and the anti-jamming are analyzed.
Single-chip microcomputer controlled stepping motor system is characterized by the flexibility, diversity in the function, accuracy in the pulse output, strong real time, low-cost, the simplify in the hardware circuit, and reliabity of the system. The software could accomplish all kinds of complicated controlling.
