A kind of overvoltage protection method of robot servo motor

Abstract

The invention relates to the technical field of servo motors, and discloses an overvoltage protection method for a robot servo motor. The overvoltage protection method involves the servo motor, an excitation device, a circuit breaker, an alarm and a flash lamp. According to the overvoltage protection method, the excitation device is a complete system, the excitation system is an indispensable partof power station equipment, the excitation system includes an excitation power source and excitation devices, the main body of the excitation power source is an exciter or an excitation transformer,and the excitation devices are composed of adjustment screens, control panels and de-excitation screens according to different specifications, models and usage requirements; in the use of the excitation devices, when an electric power system works normally, the excitation devices have additional functions such as flexible control, limitation, alarming and the like; in order to meet the above requirements, a digital excitation regulator controlled by a microcomputer is emerged and widely applied to greatly improve safe reliability and economic benefits of power plant production, and the overvoltage of the servo motor is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of servo motors, in particular to an overvoltage protection method for a robot servo motor. Background technique [0002] Servo motor refers to the engine that controls the operation of mechanical components in the servo system. It is an auxiliary motor indirect transmission device that can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor The speed is controlled by the input signal and can respond quickly. It is used as an actuator in the automatic control system, and has a small electromechanical time constant and high linearity. It produces electromagnetic interference and has requirements for the environment. Therefore, it can be used in ordinary cost-sensitive In industrial and civil applications, the servo system is an automatic control system that enables the output controlled quantities such as the p...
