Abstract
The invention relates to a device for mounting an electric motor (10) in a manner that isolates vibrations, in particular a fan motor, wherein the electric motor (10) features at least one pole housing (12, 14) serving as a magnetic yoke circuit, as well as means (26, 27) for fastening isolating elements (32, 33), in particular elastic isolating elements. In accordance with the invention it is proposed that the means (26, 27) for fastening the isolating elements (32, 33) are embodied to be a single piece with the pole housing (12, 14).
Claims17
Device for mounting an electric fan motor (10) in a manner that isolates vibrations, wherein the electric motor (10) features at least one pole housing (12) serving as a magnetic yoke ring, with means for fastening (26, 27) elastic isolating elements (31, 32, 33), characterized in that the means for fastening (26, 27) the isolating elements (31, 32, 33) include a single piece with at least one pole ring (14) of the pole housing (12).
Method to manufacture an electric fan motor (10), with at least one pole housing (12) serving as a magnetic yoke ring featuring at least the following steps:
- 1. Forming of the metal parts (28,30) forming the pole housing (12);
- and
- 2. Forming as a single piece of holding elements (26, 27) in the metal parts (28, 30) of the pole housing (12) for fastening isolating elements (31, 32, 33) for the motor (10).
