  • Cup-shaped support for an electromotor
    Patent number: 4978876
    Abstract: For equipping an electromotor to the desired extent with especially electronic elements, like radio shielding devices, a cup-shaped support (10) made of synthetic material concentrically surrounds the commutator (24), being of double-walled construction in order to provide chambers (34, 36, 38, 41) for lodging these elements. Guide channels (49, 51, 53, 55) extend from the chambers, via which electric connection lugs of the elements reach a preferably deep-drawn grid mounted on the outer surface of the support.
