DC 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 DC motor. Therefore it’s very meaningful to study the DC motor controlled system.
High-performance DC motor control system has been developed. Single-chip microcomputer is used as the CPU, SPGT62C19B is chosen as the drive of the DC motor, so the expensive exclusive controller for the DC motor could be omitted. 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 DC 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.
