ABSTRACT:
A brush mount on electric motors equipped with a radio-interference suppression choke (24), particularly for household appliances such as vacuum cleaners or the like, having a support part (7) of non-conductive material which is fastened in the motor frame (1) and into which a guide sleeve (13) of conductive material for the carbon brush (15) with its tensioning spring (17) is inserted by form lock in axially non-displaceable manner between two side walls (9, 10) extending from a web (8), the rear end of the guide sleeve (13) having a connection lug (50) for the conductor of the carbon brush (15). In order to obtain a structurally advantageous development and particularly a vibration-free holding of the guide sleeve, the free edges of the side walls (9, 10) bear a cover (28) which supports the guide sleeve (13) and that the web (8) of the support part (7) forms wings (34, 35) which protrude outward beyond the side walls (9, 10) and serve as resting surfaces for the spring-tensioning mounting on the motor frame (1) and that openings (37 and 38 respectively) are provided in the rear region of the support part (7) on both sides of the side walls (9, 10) for the mounting in locked position of the radio-interference suppression choke (24) and a plug distribution plate (42).
