Abstract

The invention discloses a high-voltage high-power stepping motor controller. The controller comprises a stepping circular impulse control circuit, an H-bridge power driving circuit, a phase current Hall sampling circuit, a phase current chopping control circuit and a protective isolation circuit. A stepping sequence signal is generated after a frequency impulse signal passes the circular impulse control circuit, and outputs a phase AB and a phase CD after being connected to the phase current chopping control circuit and the H-bridge power driving circuit sequentially. The phase AB and the phase CD drive a two-phase four-wire system stepping motor. The phase current Hall sampling circuit samples the load of the two-phase four-wire system stepping motor and acquires phase current signals. The phase current signals are output to the protective isolation circuit. The high-voltage high-power stepping motor controller has the advantages that the phase current Hall sampling circuit is adopted for phase current sampling, and the phase current chopping control circuit is combined to achieve phase current chopping treatment, so that accuracy and reliability in setting of each phase current are achieved, and the motor operates stably and has large current, less heat and low operational noise.

Description

technical field [0001] The invention relates to the field of stepping motors, in particular to a high-voltage and high-power stepping motor controller. Background technique [0002] In today's electrical age, the degree of automation in the domestic automation industry is getting higher and higher, and at the same time, there are high requirements for the controllability, sensitivity and safety performance of automatic actuators. Stepper motor Stepper motor is a special motor for control. Its rotation runs step by step at a fixed angle, that is, the step angle. It is characterized by no accumulated error, high precision, easy control, and low cost. Because of its excellent It is widely used in various open-loop control fields such as laser manufacturing, medical equipment, packaging and printing, numerical control transformation, industrial automation, etc. . [0003] The stepper motor driver is an electronic device specially used to drive the stepper motor. It converts th...
