Driver control method capable of driving plurality of stepping motors

Abstract

The invention discloses a control method of a driver capable of driving a plurality of stepping motors. Multi-path driving equipment is included, and the method is characterized in that the multi-pathdriving equipment comprises an N-type MOS tube; a voltage control device is arranged on the grid electrode of the N-type MOS tube; the input end of the multi-path driving equipment is a two-phase output signal of the stepping motor driver; and the two-phase output signal line is connected with a plurality of selection enabling signal lines in a matching manner for inputting together. The two-phase output signal lines of the stepping motor driver serve as the input end of the stepping motor driver and are matched with the multiple selection enabling signal lines for input together, and the effect that one set of two-phase output signal lines are matched with the multiple selection enabling signal lines to control the multiple stepping motors at different frequencies and stepping numbers isachieved. The production cost is reduced, troublesome external equipment is simplified, and excellent use value is achieved for autonomous products with low requirements. The control mode of multiplestepping motors is simplified, and time-sharing control over different motors can be achieved through the same stepping motor driver.

Description

technical field [0001] The invention relates to a driver control method capable of driving multiple stepping motors, belonging to the field of stepping motor driver manufacturing. Background technique [0002] Stepping motor is controlled by pulse signal, which converts point pulse signal into corresponding angular displacement and linear displacement. It is widely used in office equipment such as printers and various control devices. The commonly used stepping motor is based on electromagnetic torque Different generation mechanisms can be divided into reactive stepper motors, permanent magnet stepper motors and hybrid stepper motors, and can be divided into single-phase, two-phase, three-phase and five-phase according to the number of phases in the group. [0003] Traditional stepper motors need a driver. When the two motors are synchronous or only in opposite directions, the other speeds are consistent with the rhythm of the action, and one can drive two or more. But ther...
