Embodiment Construction

[0014] figure 1 It is a schematic diagram of the motor matrix arrangement and switch arrangement of the present invention. According to the figure, the motor winding load 1 is connected by the horizontal and vertical connection lines, and the horizontal switch 2 is connected to one side of the horizontally arranged connection line in sequence. The vertical switch 5 is arranged below the vertical wiring in sequence. The other ends are all connected to the control voltage output positive pole 3 of the stepper motor controller, and the other ends of all vertical switches 5 are connected to the output negative pole 4 . According to the above connection method, the motor to be controlled can be selected according to a certain switching logic. If the switch TA3 and TB1 are turned on, the load RA3B1 will be connected to the stepper motor controller, and other motors will be blocked. By constantly changing the combination of switches, the motor can be selected and controlled accordin...

Abstract

The invention discloses an asynchronous control stepping motor array, comprising a single stepping motor controller, a matrix array consisting of stepping motors, and a switch control device consisting of triodes or power switch devices. A computer carries out the switch logic selection and is synchronous to the output of the stepping motor. The control type of the stepping motor greatly reduces the quantity of the switch devices, only uses one controller, reduces the great asynchronous running costs of stepping motors, reduces the power dissipation and has simple logic control.

Description

technical field [0001] The invention relates to an array for asynchronously controlling a large number of stepping motors with a single controller, including a matrix arrangement of the motors and a switch control device. The switching logic selection is carried out by the computer, which is synchronized with the output of the stepper motor controller. Background technique [0002] With the rapid development of microelectronics technology, electronic computer technology, power electronics technology and material science, many new special motors with superior performance have appeared at home and abroad. Such motors (including stepper motors) have greater specificity. For example, stepping motor converts digital pulse signal into mechanical angular displacement, adopts computer-related control technology, and is used in various transportation, household appliances, electrical transmission and other automatic control fields such as weaponry and medical equipment.
