Abstract

The invention provides a servo motor and an electromagnetic friction type brake. The electromagnetic friction type brake comprises a base (3), an armature, a friction plate (4), a brake end cover anda coupler (6). A brake spring and a brake coil are installed in the base, and a guide column extending in the electromagnetic force direction of the brake coil is arranged outside the base. The brakeend cover is fixedly connected with the base, the friction plate is located between the brake end cover and the base, the armature is located between the friction plate and the base, and the frictionplate and the armature are both slidably connected with the guide column. The coupler is fixedly connected with the friction plate, and the brake spring abuts against the armature. The electromagneticfriction type brake provided by the invention can effectively improve the control precision of the servo motor.

Description

technical field [0001] The invention relates to the technical field of electromechanical products, in particular to a servo motor and an electromagnetic friction brake. Background technique [0002] In order to realize the power-off maintenance function of the servo motor, a brake needs to be installed on the motor shaft. A common type of brake is an electromagnetic friction brake. The current assembly method of the electromagnetic friction brake and the motor shaft of the servo motor is to fix it on the motor shaft. The hub is installed, and the torque is transmitted between the friction plate and the hub through a coupling. Due to the axial movement of the friction plate, it is necessary to design the friction plate and the hub as a clearance fit to ensure that the two can move relative to each other in the axial direction. [0003] The gap fit between the friction plate and the hub leads to backlash in the torsional direction. When the friction plate is locked, the motor...
