Abstract
An arrangement with an electric motor facilitates mounting of the motor, particularly of a miniature or subminiature motor. The motor (20) has a stator (56), a rotor (24), and a support flange (36) coupled to the motor. A motor mount (22) is formed with an opening (94) for engagement with the support flange (36). The opening has, on its rim, a motor-side shoulder (96) that has a substantially frustoconical shape and faces axially toward the motor (20) after mounting. The support flange (36) is shaped for guidance of a snap-lock element (82) that extends along at least a portion of the circumference of the support flange (36) and is resiliently deflectable radially inward, by means of an inwardly directed force. The snap-lock element (82) is so configured that it snap-locks outward against the motor-side shoulder (96) of the opening (94) when the motor is mounted.
