Modularized whole-disc multi-disc electromagnetic brake

The invention relates to a modularized whole-disc multi-disc electromagnetic brake, and belongs to the technical field of brakes. The motor comprises a stator, a rotor and an electromagnet. The rotor is rotationally mounted in a shell inner hole of the stator so as to be connected with the power shaft; a plurality of brake cavities distributed at intervals are formed in an inner hole of a shell of the stator; each brake cavity is internally provided with a brake disc and a friction plate which form a friction pair, and electromagnets are installed on the inner walls of the brake cavities and used for magnetically attracting the brake discs. A brake spring is connected between the electromagnet and the brake disc; the inner circles of the friction plates and the rotor are restrained in the circumferential direction and form a moving pair in the axial direction, the brake discs and an inner hole of a shell of the stator are restrained in the circumferential direction, and elastic pieces are arranged between the
