Claims

[Scope of utility model registration request]

(1) A brake lining loosely fitted and supported by a hub fixed to a rotating shaft, a pressing plate disposed opposite to the end face of the brake lining so as to be able to move toward and away from it, and a pressing plate that presses the pressing plate in the direction of the brake lining. In an electromagnetic brake for an electric motor, which consists of an electromagnet with an excitation coil that releases pressure, and a control spring that presses a pressure plate in the direction of the brake lining,
An electromagnetic brake for an electric motor, characterized in that a part of the outer circumferential portion of the brake lining is cut out, and the hub is provided with a protrusion or a notch corresponding to the amount of unbalance around the rotating shaft caused by the notch.

(2) Utility model registration scope In the electromagnetic brake according to claim 1, in which the hub is fixed in the rotational direction of the rotating shaft by a key, a protrusion provided on the hub is aligned with the key. An electromagnetic brake for an electric motor characterized by:

(3) Utility model registration In the electromagnetic brake described in claim 1, one or more protrusions are provided on the hub, and by removing part or all of the protrusions by processing, etc. An electromagnetic brake for an electric motor characterized by being combined with a brake lining having an unbalanced amount.
