モータ。[Claims for Utility Model Registration] (1) A rotor assembly comprising a housing to which a permanent magnet stator is attached, a shaft and a commutator, and a wire-wound armature firmly attached to the shaft, The shaft rotates in bearings mounted on opposite ends of the housing, and a brush gear is mounted on the frame and has brush bearings on the commutator for supplying current from the power supply to the armature windings. In a fractional horsepower permanent magnet DC motor, the housing has an opening in the vicinity of the commutator, which opening is joined on one side by a rim extending around the motor shaft and connected to the frame. is attached to the rim and is movable along the rim around said shaft, and means are further provided for moving the frame along the rim and for placing the frame in a fixed position on the rim. A DC motor, characterized in that it is provided with means for holding it. (2) The motor according to claim 1, wherein each of the brushes is supported by one end of a brush leaf, and the other end of the brush leaf is supported by a frame. (3) The motor according to claim 1 or 2, wherein the spring is attached to the frame and hits the brush leaf to press the brush against the commutator. 4. A motor according to claim 1, 2 or 3, wherein the rack is provided on the frame and the pinion is attached to the housing. (5) The motor according to any one of claims 1 to 4, further comprising means for fixing the pinion in position so as to fix the frame on the rim. 6. A motor according to claim 1, wherein the frame is attached to a removable end cap of the housing, the end cap supporting the bearing. (7) A motor according to any one of claims 1 to 6, wherein the frame is made of plastic material. 8. A motor according to claim 1, wherein said housing has a cylindrical cast part supporting said magnet, said cast part being formed by a stack of laminations. (9) The motor according to claim 8, wherein the outer surface of the stack is provided with ribs. (10) The motor according to claim 9, wherein the outer surface of the stack is castellated. (11)11 The end of the housing near the commutator has an end cap supporting the bearing for the motor shaft, the end cap having a circular rim disposed in a plane transverse to the shaft. , and a plurality of legs extending axially from the rim to the bearing housing, the frame being attached to the rim. (12) 12 The motor of claim 11, wherein the frame straddles an arcuate wall of the rim, the wall extending along an arc around the motor axis. (13) 13 The motor according to claim 12, wherein the brushes are pressed against the commutator by a spring whose pressure can be adjusted. (14) 14 The motor according to any one of claims 1 to 13, wherein the means for moving the frame is toothed. 〓(15)１５〓 The above means of moving the frame is
15. The motor of claim 14 comprising a rack and pinion.
