This kind of structure facilitate by yoke be embedded in end cap ontology in, while ensure yoke it is more solid and reliable be mounted on end cap In ontology.

Preferably, it is equipped with the spacing collar of fitted bearing lid on the right side of the end cap ontology, installation is equipped on the outside of the spacing collar Circle.

This kind of structure not only facilitates bearing cap to be mounted on end cap ontology, while end cap ontology being facilitated to be mounted on motor.

Preferably, the quantity of the screw is three, and three screws are distributed in equilateral triangle, and the yoke is equipped with cooperation The bearing mounting groove of bearing.

This kind of structure further ensures that the degree of firmly installing of bearing cap and yoke, while further ensuring that the installation jail of bearing Soundness.

A kind of braking method of the servo motor end cap of band brake, 1) coil obtains electric, and yoke generates magnetic force by armature It is sucked, armature against the force of the spring is moved toward yoke direction, and brake disc is released, at this point, shaft can be normal with brake disc Rotation；2) coil losing electricity, armature under the spring-force driven dual of spring to brake disc direction move, brake disc be locked in quiet plate and It can not be rotated between armature, at this point, brake disc limitation shaft can not rotate, reach braking purpose.
