[0005] One axial end of the commutator is plugged into the rotating shaft, and the other end is exposed to the outside. When the carbon brushes are in contact with the commutator segments of the commutator, the exposed end of the commutator is prone to arcing, and the arc along the commutation The axial extension of the sheet will affect the internal parts of the motor

Embodiment Construction
[0013] Such as figure 1 The shown commutator with an insulating device includes a columnar plastic body 1 and commutator segments 2 evenly distributed on the outer peripheral surface of the columnar plastic body 1, and the middle part of the columnar plastic body 1 is provided with a mounting for the installation of the rotating shaft. The hole 11, the axial direction of the columnar plastic body 1 is the installation end 12, and the other end is the arc extinguishing insulation end 13, and the arc extinguishing insulation end 13 is provided with an insulating sheet 3 detachably connected with the columnar plastic body 1, and the outer surface of the insulating sheet 3 The edge is on the same plane as the outer edge of the commutator segment 2. In the above scheme, by setting the insulating sheet 3 whose edge is on the same plane as the edge of the commutator segment 2 at the arc-extinguishing insulating end 13 of the columnar plastic body 1, the insulating sheet 3 can prevent...

The invention relates to a commutator for a motor, and more particularly to a commutator with an insulating device. The invention provides the following technical scheme: the commutator with the insulating device comprises a columnar plastic body and commutator segments uniformly distributed on the outer peripheral surface of the columnar plastic body; a mounting hole for mounting a shaft is provided in the middle part of the columnar plastic body; the axial direction of the columnar plastic body is a mounting end, and the other end is an arc-extinguishing and insulating end; an insulating sheet which is detachably connected to the columnar plastic body is arranged at the arc-extinguishing end of the columnar plastic body; and the outer edge of the insulating sheet is in the same plane asthe outer edge of the commutator segments. By adopting the above technical scheme, the commutator with the insulating device which can extinguish arc, insulate and prevent arc damage to internal components of the motor and has a simple structure is provided.
Description
technical field [0001] The invention relates to a commutator for a motor, in particular to a commutator with an insulating device. Background technique [0002] Motor commutators are divided into planar commutators (that is, the body of the commutator is perpendicular to the axis of rotation of the commutator) and cylindrical commutators (that is, the rotation of the body of the commutator and the commutator axis parallel). [0003] The cylindrical commutator is mainly composed of a cylindrical plastic body and copper commutator segments evenly distributed on the peripheral surface of the cylindrical plastic body. The middle part of the cylindrical plastic body is provided with a hole for the installation of the rotating shaft. [0004] During use, the carbon brushes in the motor are in contact with the copper commutator segments of the commutator to achieve commutation. [0005] One axial end of the commutator is plugged into the rotating shaft, and the other end is expos...
