Servo motor with inertia disk and installation method for servo motor

Abstract

The invention relates to a servo motor with an inertia disk and an installation method for the servo motor. The servo motor with the inertia disk comprises a shell, a stator and a rotor, wherein a front end cover and a rear end cover are arranged at the front end and the rear end of the shell; the inertia disk is arranged on the rotor; the inertia disk is located between the stator and the rear end cover; the stator is fully filled with a potting adhesive to become a potted stator; a wire fixing body which is formed by potting protrudes on the rear end surface of the potted stator; a wire led out from the stator penetrates through the wire fixing body and is led out of the shell; and the wire fixing body is located between the shell and the inertia disk. The installation method comprises the steps as follows: a front bearing, the rotor, the inertia disk, a rear bearing and the rear end cover are arranged to form a component A; the shell, the stator and the front end cover are potted to form a component B after being installed; the component A is enclosed into the component B from the rear end of the shell; and an encoder and a rear cover are arranged. According to the servo motor, the inertia of the motor can be conveniently increased to drive a heavy load; the inertia can be flexibly adjusted; time and labor are saved; the cost is reduced; and the servo motor is simple to assemble and convenient to install.

Description

technical field [0001] The invention relates to a servo motor, in particular to a servo motor with an inertia disk which is convenient to adjust the inertia and simple to assemble and an installation method thereof. Background technique [0002] In the application of servo motors, the matching of motor inertia is involved. Because in the case of large load inertia, the use of low inertia motors cannot meet the requirements, so it is necessary to select a servo motor with corresponding inertia according to the load inertia. The traditional way to change the inertia is to redesign a motor and increase the rotor inertia by increasing the diameter of the rotor, but this method will cause a complete change in the electromagnetic scheme and structure of the motor, and once the rotor is formed, the inertia is fixed and cannot be done. If it needs to be changed, the motor must be redesigned, which cannot be adjusted flexibly, which is time-consuming and laborious, and increases the ...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the technical problem that the change of the inertia of the original motor is achieved by changing the diameter of the rotor. Once the rotor is formed, the inertia is fixed and cannot be changed. The inertia adjustment is neither flexible nor convenient, which is very time-consuming and labor-intensive, and also increases the technical problem of cost. ;Provide a servo motor with an inertia disk, the rotor inertia can be adjusted by changing the size of the inertia disk, the inertia adjustment is flexible and convenient, it saves time and effort, and also reduces the cost, and there is no need to redesign the motor, and it will not affect the motor. The electromagnetic scheme and the overall structure are changed, so the motor has better stability and reliability
