The invention relates to an electromagnetically released spring-applied brake with anchor plate. Said brake comprises a brake rotor (2) which is impinged upon by the anchor plate (6, 8), can be axially displaced and is forced against a frame-fixed abutment (4). The anchor plate (6, 8) is subdivided into a front anchor plate (6) and a rear anchor plate (8) of which only the front anchor plate (6) impinges upon the brake rotor (2). The rear anchor plate (8) engages in a recess (7) of the front anchor plate (6). The two anchor plates (6, 8) are linked with each other in a non-rotational manner and can be axially displaced with respect to each other. The rear anchor plate (8) rests on supporting members (15) at the magnet part (11). The front anchor plate (6) and the rear anchor plate (8) are each opposite one of the poles of a magnet part (11) with corresponding antipole surfaces. Pressure springs (9, 10) act upon the anchor plates (6, 8). Said pressure springs are arranged partially in the internal pole (12) and partially in the external pole (13) of the magnet part (11). The inventive brake functions like a brake with a one-piece anchor plate in the normal operation. In the case of an emergency, the brake has sufficient braking effect.
