Abstract: The motor has two motor flanges (1,2) which form the stator with stator magnets projecting axially inward from the inner sides (11,12) of the flanges, the magnets being distributed along a circle coaxial with the motor axis, and a slightly conical rotor (9) in the air space between opposing stator magnets (11,12). On the output side of one motor half, and facing outwardly, is an annular space defined by the stator magnet (11) on the output side of the motor flange (1). A blocking brake (18 to 23) is mounted in a space-saving manner, with the stationary half of the brake (18 to 21) placed in an opening made for it in the outer flange piece (18) in the motor flange (1) and attached to it. The rotating half of the brake (22,23) is attached to the motor shaft (6). In this way, the motor and friction brake form a compact structural unit whose dimensions are not greater than those of an ordinary motor housing.
