Abstract

A small motor consisting of The housing is assembled with a permanent magnet which has been installed. Fixed on the inner perimeter of the housing, rotor consisting of Armament and commutator steel core and integrated housing cover, power brush and input connector. By assembly pieces A connection made of conductive material is provided on the inner end face of such a housing cover; The connecting assembly is connected either directly to one of the input terminals or through Through other conductive components; Another connector assembly and another connector are attached to the brush. Through the braided wire braid; The torsion spring arm is exposed to the outer end. Of the brush in such a way that the brush will be pushed against the commuter; And the braids wire will be wrapped around the arm.

Claims (2)

1. A small motor with an integrated housing (1) made of metal material. Which has been formed in the shape of a hollow tube with a bottom and There are permanent magnets (2,2) which are fixed fixed to the inner perimeter of the housing, rotor (5) with an armature iron core (3) facing the permanent magnet (2, 2) thereof and the commutator (4) and the housing cap (6) attached to the exposed end of the housing (1); A pair of brush holders (15,15) for holding brushes (45,45) making sliding contacts to the said commutator (4) and a pair of welded input terminals (8,8). Electrical connection to the brush (45,45) as mentioned via Braided wire (14,14) or via another supplied conductive assembly. On the aforementioned cover (6); Such rotors (5) are supported in such a way that they can be rotated by bearings, each of which is aligned. Prepared on the bottom of the aforementioned case (1) and the aforementioned cap (6), unique in that A pair of connecting assemblies (16,16) made of conductive material is provided on the serrated surface. The inner end of such a bezel (6) in a state of insulation and in a symmetrical manner with respect to the point when Relative to the axial condition of the motor; One connecting assembly (16) is connected to one input terminal (8) through a connector. A resistance with a positive temperature coefficient (49) and another connecting assembly (16) are connected to With another input connector (8) directly; The brush (45,45) is connected to another connector assembly (16) or another input connector (8) with a pigtail braid (14,14); The brush (45,45) is loaded by bringing the arm (13a, 13a) of the torsion spring (13,13) into contact with the outer end of the brush (45,45) in such a way. That such brushes (45,45) would be forced onto such (4) computers; And the aforementioned braided wire (14,14) is wound around the arm (13a, 13a) of the torsion spring (13) 2. Small motor as mentioned in claim 1 where the capacitors (50) will be connected. Astride the above (16,16) connecting assembly.
