In at least one embodiment of the present invention a bell-armature coil for an electric motor is provided. The bell-armature coil comprises a hollow-cylindrical coil winding which forms a coil opening at one end and is wound from a winding wire. The bell-armature coil further comprises a coil former plate. The coil former plate includes a printed circuit board. Into the coil opening the coil former plate is inserted. The coil winding has conductor ends which are connected to the printed circuit board.

Retaining device for an electric motor

The present invention relates to an arrangement for the vibration-isolating mounting of an electric motor (2) on a support part (6) via an essentially disk-shaped support element (12). The support element (12) has a motor-holding section (24) for connection to the electric motor (2) and a support-holding section (26) for connection to the support part (6), and the two holding sections (24, 26) are connected via elastic, web-like connecting pieces (28). The connecting pieces (28) are designed such that the two holding sections (24, 26) are elastically movable relative to each other three-dimensionally in all directions in space, specifically axially, radially and tangentially, over a certain movement play. The support element (12) has integrated stop means for the three-dimensional limiting of the elastic relative movements of the holding sections (24, 26) and/or an additional mass (110) to influence the vibration behavior.

Arrangement for the vibration isolating mounting of an electric motor

An electric motor includes a generally tubular housing portion having an outer surface; a plurality of fixedly held support bases spaced circumferentially about the housing portion and being at a radial distance from the outer surface of the housing portion; and a plurality of elastic elements, each being secured to the outer surface of the housing portion and to a separate one of the support bases for supporting the electric motor by the housing portion and for suppressing excitation oscillations generated by the electric motor during operation thereof. The elastic elements together form a suspension system which is tuned to the excitation oscillations of the electric motor such that the natural frequency of the suspension system is less than the excitation frequency of the electric motor.
