Brake, brake motor and automation equipment

The utility model provides a brake, a brake motor and automation equipment. The brake comprises at least one electromagnetic assembly not arranged on a motor shaft in a sleeving mode, a moving assembly and at least one elastic assembly connected with the moving assembly in an abutting mode. The moving assembly is used for carrying out displacement switching between a first position critical point and a second position critical point along the axial direction of the motor shaft according to the state change of the elastic assembly; the braking assembly is used for realizing braking or non-braking of the motor shaft through the change of the first position critical point or the second position critical point of the moving assembly; when the brake is powered on, at least part of the magnetic field generated by the electromagnetic assembly is not on the motor shaft. According to the technical scheme of the utility model, a central axial magnetic field generated by the brake can be effectively solved, so that the
