Description
Technical Field
The utility model relates to a processing device of a permanent magnet brake, in particular to a running-in device of the permanent magnet brake, and belongs to the technical field of motor manufacturing.
Background
The permanent magnet brake for the servo motor is generally of a split structure, namely, the permanent magnet brake is divided into a brake stator and a brake rotor. The brake stator is fixed on the end cover of the motor, and the brake rotor is fixed on the motor shaft. The brake rotor is connected together by armature, spring plate and shaft sleeve through rivet. When the coil of the brake stator is not electrified, the armature of the brake rotor is attracted to the brake stator under the action of the magnetic steel of the brake stator, so that the braking effect is achieved; when the coil is electrified, the attraction force between the armature and the brake stator is very small due to the counteracting effect of the coil magnetic field and the magnetic steel magnetic field, the armature and the brake stator can be pulled apart through the spring piece on the brake rotor to form an air gap, and the brake rotor can freely rotate at the moment.
Permanent magnet brakes typically require sufficient wear of the armature to brake stator interface to maintain adequate torque for long periods of time. The general running-in method is to make the brake rotor always keep rotating, to make the coil alternatively power-on and power-off, to make the brake be in the 'inching brake' state, after circulating for a certain number of times, to test the brake torque, if it reaches the set torque, it is qualified. Running-in is a great difficulty in manufacturing the permanent magnet brake and is also a great pain point for a brake user. The conventional running-in needs a motor to drive a brake rotor to rotate, an external circuit is needed to control the opening and closing of a brake, and a torque sensor is needed to test the torque or a torque wrench is used for manually testing the torque. The main problems are that the installation is complicated and the efficiency is low. The adaptability to permanent magnet brakes of different specifications is poor, and a relay of an external circuit and a torque sensor for testing torque are easy to damage.
