Abstract
The invention relates to a device (10) for accommodating an electric motor (30), particularly a blower motor for a heating or air-conditioning system, comprising an essentially pot-shaped accommodating housing (12) serving as a motor housing and having an accommodating opening (32) in which the pole casing (46) of an electric motor (30) can be inserted while at least partially projecting inside. The inventive device also comprises a retaining flange (14) mounted on the accommodating housing (12) and serving to fasten the motor housing (12) to a supporting element, and comprises a control and regulating unit (20) mounted on the retaining flange (14) and serving to operate the electric motor (30). The invention provides that the accommodating housing (12) has, in the peripheral direction, at least one flattened area (36,40), which differs from a circular shape while corresponds with at least one flattening (54) of an outer contour of the control and regulating unit (20). The invention also relates to an electric motor (30), particularly a direct-current motor having at least two permanent magnetic poles (44) and a pole casing (46) serving as a magnetic return ring and having at least…
