Background

A stepping motor is an electric motor that converts an electrical pulse signal into a corresponding angular or linear displacement. The rotor rotates an angle or one step before inputting a pulse signal, the output angular displacement or linear displacement is proportional to the input pulse number, and the rotating speed is proportional to the pulse frequency. Therefore, the so-called incremental position control system, in which a stepping motor is also called a pulse motor and which can be controlled by the position of an open loop to obtain a predetermined position increment by inputting a pulse signal, is significantly reduced in cost as compared with the conventional dc control system, requires almost no system adjustment, has an angular displacement amount strictly proportional to the number of pulses inputted and is synchronized with the pulses in time, and thus can obtain a desired rotation angle, speed and direction by controlling the number of pulses, the frequency and the phase sequence of the motor windings.

The existing protective cover plate of the stepping motor and the stepping motor have small effects, and the actual protection on the stepping motor is weak, so that the protective cover plate cannot be really applied to a working field, and the protective cover plate is only used for solving the problems that the stepping motor is prevented from falling ash on the surface when being idle, and cannot help the stepping motor in work.
