Embodiment Construction

[0029] refer to figure 1 , figure 2 and image 3 , The brushed motor 100 provided by the embodiment of the present invention is a DC brushed motor, including a stator and a rotor. The stator includes a housing 60 , a permanent magnet 62 mounted to the inner wall of the housing 60 , and an end cover 61 fixed to the open end of the housing 60 . The permanent magnets 62 form six stator poles of the stator. If P is used to represent the number of stator pole pairs, then P is three. An L-shaped connecting part 66 is mounted on the outer wall of the housing 60 , and the L-shaped connecting part 66 has a through hole 67 for fasteners to pass through to install the brushed motor 100 . A brush holder 63 is installed on the end cover 61 , and a brush 64 is installed on the brush holder 63 .

[0030] The rotor includes a rotating shaft 70 , a rotor core 71 coaxially fixed to the rotating shaft 70 , and a commutator 72 . The rotor is installed in the housing 60, and the rotating sha...

Abstract

The invention provides a brush motor including a stator and a rotor. The rotor includes a rotary shaft, a rotor magnetic core fixed to the rotary shaft and a commutator. The commutator includes an insulation base and a plurality of commutator bars fixed on the insulation base. The stator is provided with 2*P stator electrodes and the rotor has m teeth, wherein P is an integer greater than 1, m isgreater than 2P and smaller than 4P and 2m is the integral multiple of P. A rotor winding of the rotor is a centralized winding provided with m first elements and m second elements. Each tooth is coiled with one first element and one second element. The m first elements form a plurality of element sets. Each element set is provided with n first elements connected in series. Merely two ends of eachelement set are connected to a corresponding commutator bar. n is greater than or equal to 2 and is smaller than or equal to P. Two ends of each second element are connected to a corresponding commutator bar. By applying the invention, motor production efficiency can be improved and production efficiency can be reduced.

Description

technical field [0001] The invention relates to the electric field, and more specifically relates to a cooling module and a brushed motor thereof, which can be used to cool the engine of a car. Background technique [0002] A brushed motor consists of a stator, usually fitted with permanent magnets to form the stator poles, and a rotor, which has rotor windings to mate with the stator poles. Specifically, the rotor includes a rotating shaft, a commutator fixed to the rotating shaft, and a rotor magnetic core. The rotor magnetic core has a plurality of teeth protruding outward, and wire slots are formed between adjacent teeth. The rotor winding is wound on the corresponding teeth, its effective side falls into the corresponding wire slot, and its wire end is conductively connected with the commutator segment of the commutator. [0003] There is an existing motor with 6 stator poles and 9 wire slots, which adopts a centralized winding method, and each tooth is wound with two ...
