Abstract

The invention discloses a three-phase high-speed step motor driver with a full step angle of 2.4 degrees. The three-phase high-speed step motor driver comprises a master control CPU (central processing unit), a pulse control signal input interface circuit, a current sampling unit and regulating unit, a switch power supply and power input EMI circuit, a 6-way PWM (pulse width modulation) signal output isolation circuit, a master control power module and auxiliary circuit, a step motor three-phase winding U/V/W output end, a power-on sequence control circuit and a power-down parameter storage unit. In the automatic equipment application field, an application speed range of a traditional step motor driver is expanded by 30-50% under conditions with requirements of positioning or speed regulating, and irreplaceable application solution schemes are provided in some positioning control with requirements of frequent forward and reverse rotation, so that equipment production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a stepping motor driver, in particular to a three-phase high-speed stepping motor driver with a full-step step angle of 2.4°. Background technique [0002] With the vigorous development of the field of industrial automation, stepper motors and drivers are more and more widely used in automation equipment. It is mainly due to the simple wiring of the stepper motor, the ease of use in occasions requiring positioning control, the high degree of localization, and complete supporting facilities. In the application of hybrid stepper motors with 86 bases and 110 and 130 bases (the main demand point is within 900RPM, high torque, high response, cost-effective positioning control, or frequency conversion speed control), three-phase hybrid Stepper motors are the most widely used. In the case of higher speed requirements, usually only servo motors and drives are used to achieve positioning and speed control. [0003] The full-step step...
