Electromechanical drive

An electromechanical drive (1) comprising

• a motor (2),
• a rotational part (3), said rotational part being rotatable by the motor (2) about a rotational axis (4), and
• a braking device (5) that can be actuated between a braking position and a released position,
• the braking device (5) having a brake disc (6) that rotates with the rotational part (3) and a braking element (7) that can be adjusted in the axial direction and acts on the brake disc (6) in the braking position,
• wherein the brake disc (6) has
• an inner area (8),
• a friction surface area (10) extending annularly around the rotational axis (4) with a first friction surface (11) formed on a first side of the brake disc (6), and a second friction surface (12) formed on a second side of the brake disc (6) opposite the first side, and
• an intermediate area (9) extending between the friction surface area (10) and the inner area (8) around the rotational axis (4),
• and wherein a first mating surface (17) is formed on the braking element (7), which mating surface faces the first friction surface (11) and interacts with the first friction surface (11) in the braking position, and
• wherein the friction surface (10) of the brake disc (6) is arranged between the first mating surface (17) and a second mating surface (18) which faces to the second friction surface (12) and cooperates with the second friction surface (12) in the braking position,
• wherein the intermediate area (9) is a deformation area that is elastically deformable in the axial direction by the action of the braking element (7) on the brake disc (6), and
• wherein, in the released position of the braking device (5), the first surface (11) and the first mating surface (17) deviate from a parallel alignment and/or are inclined towards each other and/or the second friction surface (12) and the second mating surface (18) deviate from a parallel alignment and/or are inclined towards each other.
