Technical Field

The invention relates to the field of stepping motor driving equipment, in particular to a stepping motor driver suitable for mechanical engineering.

Background

The stepping motor is an open-loop control motor which converts an electric pulse signal into angular displacement or linear displacement, is a main executive element in a modern digital program control system, and is extremely widely applied. In the non-overload condition, the rotation speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not influenced by the load change, when the stepping driver receives a pulse signal, the stepping driver drives the stepping motor to rotate by a fixed angle in a set direction, namely a stepping angle, and the rotation of the stepping motor is operated by one step at the fixed angle.

The stepping motor can control the angular displacement by controlling the number of pulses, thereby achieving the purpose of accurate positioning; meanwhile, the rotating speed and the rotating acceleration of the motor can be controlled by controlling the pulse frequency, so that the aim of speed regulation is fulfilled. The step motor is an induction motor, and its working principle is that it utilizes electronic circuit to change the direct current into time-sharing power supply, and utilizes multiphase time sequence to control current, and uses said current to supply power for step motor, and the step motor can normally work, and its driver is a multi-phase time sequence controller for time-sharing power supply of step motor.

As a common transmission element, a stepping motor is widely used in the field of mechanical engineering. Before data analysis is performed in a laboratory, practitioners in the mechanical profession need to assemble and connect supporting devices such as stepping motors and drivers, which is time-consuming and labor-consuming. In order to improve the experimental efficiency, the driver of the stepping motor is improved and is suitable for mechanical engineering.
