Stepper motor is a large number of motor, and is a kind of relatively special motor, both working principle and use are all difference with ordinary motor, is in the early days of the general motors began when the popularization and application of the developed and gradually appear. To produce and development of this kind of motor, this paper introduce simple for everybody: the origin of the original model of stepper motor is an earlier time, the early twentieth century in the phone automatically switches are widely used in the stepper motor. This society in the western capitalist powers for the colony alarm, the stepping motor of ships and planes in the absence of ac power independence has been widely used in the system. By the late 1950 s, the transistor was invented, and gradually applied in the motor, yes for digital control easier. So after the development in the eighty s, cheap miniature computer began to appear, with a variety of functions of a microcomputer stepping motor control method is more flexible, so the motor technology and quality level has been effectively promoted, is becoming more and more widely applied. In simple terms, the formation and development history of stepping motor is such, see its time is longer. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
