Description

Servo motor with encoder

Technical Field

The utility model relates to the technical field of motors, specifically a servo motor with encoder.

Background

At present, the servo motor with the encoder is unreasonable in structure, the encoder and the motor body are located in the same space, when the motor needs to be disassembled, the motor needs to be opened in a whole mode, and maintenance and part replacement are not facilitated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a servo motor with encoder in order to solve current problem.

The utility model discloses a technical solution measures as follows:

the utility model provides a servo motor with encoder, includes shell, rotor and stator, the rotor is established at the shell middle part, the rotor is provided with outward the stator, the fixed encoder that is provided with in shell lower part, the encoder with the stator electricity is connected, the encoder outside is provided with the guard shield, be connected with the second lead wire on the encoder, second lead wire end electricity is connected with the second connector, the second lead wire passes the guard shield, the second lead wire with the fixed second clamp plate that is provided with in guard shield junction outside, the point connection has first lead wire on the stator, first lead wire end electricity is connected with first connector, first lead wire passes the shell, first lead wire with the fixed first clamp plate that is provided with in shell junction outside.

Preferably, a second end cover is arranged between the housing and the shield, and the second end cover is fixedly connected with the housing.

Preferably, a sealing gasket is arranged between the second end cover and the shield, so that the sealing performance of the motor is improved.

Preferably, a wave pad is disposed between the second end cap and the housing.

Preferably, the upper part of the shell is provided with a first end cover for protecting the upper end face of the motor shell.

The beneficial effects of the utility model reside in that: the utility model discloses saying electron rotor and encoder setting in two spaces, when the encoder goes wrong, only need open the guard shield, maintain or change the encoder, when needs go on to motor body to the maintenance, only need open the shell and look over the processing to stator or rotor, consequently the utility model discloses the part distributes rationally, is convenient for maintain and change.
