| Zusammenfassung: | The utility model discloses a banister motor braking device, including the brake lever, the brake lever is lifted up or is put down by a motor drive, the brake axle is worn out to form by the bottom by the main shaft of motor, the motor bottom surface is fixed with an electro -magnet, the brake axle is provided with a ferromagnetism brake pads, the ferromagnetism brake pads by an elastic construction setting on the brake axle, when electricity on the electro -magnet, the ferromagnetism brake pads is inhaled and is pasted on the electro -magnet surface and make elastic construction elastic deformation, during the electro -magnet outage, elasticity structure recovery just makes ferromagnetism brake pads and electro -magnet separation. The utility model has the advantages of the ability active absorption comes from the produced brake lever shake and the impact of inertia of brake lever and motor to can improve the operation precision of brake lever.
