ABSTRACT:
An electrical apparatus such as a disc-record player, comprises a mounting device for a drive motor (7). The motor housing (6) is resiliently suspended on fixed motor supports (4) in the housing (1) of the apparatus so as to be in a radial direction with respect to the motor axis (7a). For this purpose suspension rings (11) of an elastic and vibration-dampening material are fitted around mounting elements (10) on the motor housing (6) and around the motor supports (4). The motor housing (6) carries stop portions (13) which in the event of axial movement of the motor housing (6) abut against fixed abutment surfaces (14) inside the housing (1) to limit said movement. Positioning means (15,20) are provided, which position said stop portions (13) and abutment surfaces (14) in such a way relative to each other after turning of the motor housing (6) and stretching of the suspension rings (11) that the stop portions (13) can move freely along the abutment surfaces (14) in an axial direction.
