DC brushless motor is mainly by rotating shaft, rotor assembly, stator module, casing, end cap and control circuit Plate forms, and rotor assembly is arranged in rotating shaft, and stator module and casing are installed together and are nested in rotor set Outside part, end cap is arranged on the end of casing, and rotating shaft two ends are bearing in respectively on the bearing of end cap and turn Axle two ends are past in the middle of two end cap respectively to be overhang, and control circuit board is arranged on the sky surrounded by end cap and casing Inside chamber.

Along with the lifting of people's demand, generally require now multiple motor and work together and could meet requirement.But In prior art, when multiple motors work together, simply simply motor is stacked, motor and electricity Phase mutual friction between machine, and when motor is mutually installed, less stable.

Utility model content

In view of above-mentioned condition, it is necessary to provide one to be easy to motor stacking, stability preferable brush DC electricity Machine.

A kind of DC brushless motor, including rotating shaft, casing, drive end bearing bracket, rear end cap, rotor assembly, stator Assembly and control circuit board, the surface of described casing both sides attaches layers of two-sided, and described layers of two-sided is dorsad Cushion is pasted in the side of described casing, and described rotor assembly is arranged in described rotating shaft, described stator module Be installed together with described casing, and be nested in the outside of described rotor assembly, described drive end bearing bracket and described after End cap is arranged on the end of described casing, and the two ends of described rotating shaft are bearing in described drive end bearing bracket and described respectively On the bearing of rear end cap, and the two ends of described rotating shaft are past from the centre of described drive end bearing bracket and described rear end cap respectively Overhanging, described control circuit board is arranged on inside the cavity surrounded by described drive end bearing bracket and described casing.

Wherein in an embodiment, described cushion is rubber buffer.

Wherein in an embodiment, the thickness of described rubber buffer is less than the thickness of described casing.

Wherein in an embodiment, described cushion is spongy layer.

Wherein in an embodiment, described spongy layer is shaped as round square or irregular shape by several The sponge composition of shape.

The DC brushless motor that the utility model proposes passes through to attach layers of two-sided in the both sides of casing, and double The side stickup cushion of face glue-line casing dorsad, simple in construction, it is possible in the case of number of motors is more, Ensure not to be moved between motor, it is simple to the stacking of motor, and need not motor stacking when, only Layers of two-sided or cushion need to be torn off, it is easy to cleaning.
