The welding of the mounting support legs of the motor is firm and reliable; an auxiliary safety device is made of tensile resistant material and has high safe coefficient; and the motor is convenient and flexible in installation, can be matched with air conditioners or directly applied to large vehicle such as luxurious sight seeing buses, public buses and large passenger ships.

Description

The ceiling fan permanent magnet direct current motor

Technical field

The utility model relates to the motor that a kind of ceiling fan is used, and specifically relates to the ceiling fan permanent magnet direct current motor that moves under a kind of direct current safe voltage.

Background technology

Usually ceiling fan adopts the single phase capacitor operating type asynchronous motor with motor, and its structure comprises end cap, bearing, rotating shaft, armature winding and casing etc.Domestic at present, generally have two types with the fixture of ceiling fan motor connection, a kind of is that its longitudinal section is lay across arc, and a kind of is plate, usually adopt bolt or other securing members directly to be fixed on the motor, motor directly is connected with ceiling by securing member again.But, being subjected to the long-term vibration of motor or other cause influence, motor is loosening easily, has certain potential safety hazard.

The utility model content

The utility model provides a kind of security protection coefficient high ceiling fan permanent magnet direct current motor.

A kind of ceiling fan permanent magnet direct current motor, comprise casing, armature winding, magnetic shoe, brushgear, commutator, rotating shaft and end cap, be fixed with armature winding, magnetic shoe, brushgear, commutator and rotating shaft in the casing respectively, end cap is installed in the casing opening, the rotating shaft output passes described end cap, and its design feature is also to be provided with at least two on the described casing leg is installed, have the pointed projections point on the installation leg, the pointed projections point that leg is installed is connected with the casing solid welding.

The pointed projections point of described installation leg highly is at least 0.5 millimeter.

Also be provided with the auxiliary security protector of being made by steel wire rope on the described casing, the auxiliary security protector has two free ends that connect motor and ceiling respectively.

Also be equipped with power line on the described end cap, power line is electrically connected with armature winding.

Described end cap is provided with the concave part that can receive carbon dust, the sliding contact position between corresponding commutator in concave part and the brush.

The beneficial effects of the utility model are, the carbon dust that commutator and brush sliding contact wearing and tearing produce can be deposited on the end cap recessed portion, the possibility that has reduced short circuit and entered bearing and rotating shaft contact position, special structural manufacturing process is adopted in the welding of described installation leg, discharging structure when being provided with pointed projections point as welding, make the junction that enough molten metal baths be arranged, guaranteed the solid and reliable of welding, motor fell and causes injury or electric leakage to human body to cause fire when the auxiliary security protector can prevent that hoisting structure from getting loose, improved the security of products energy, the power line of armature winding extends into from front end housing, conveniently determine best electric fan mounting points, needn't be limited by the position of external power supply line interface.The utility model also can cooperate air-conditioning to use or directly apply to some large-scale vehicles such as luxury travel car, public bus, flagship etc. in, strengthened the circulation of air in these spaces.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Ceiling fan comprises casing 1 with permanent magnet direct current motor, armature winding 2, magnetic shoe 4, brushgear 5, commutator 6, rotating shaft 8 and end cap 7, be fixed with armature winding 2 in the casing 1 respectively, magnetic shoe 4, brushgear 5, commutator 6 and rotating shaft 8, end cap 7 is installed in casing 1 opening, rotating shaft 8 outputs pass described end cap 7, also be provided with at least two on the described casing 1 leg 301 is installed, install on the leg 301 and have pointed projections point 11, the pointed projections point 11 that leg 301 is installed is connected with casing 1 solid welding, discharging structure when being provided with pointed projections point 11 as welding, make the junction that enough molten metal baths be arranged, guaranteed the solid and reliable of welding.

The pointed projections point 11 of described installation leg 301 highly is at least 0.5 millimeter.

As preferred embodiment, further, also be provided with the auxiliary security protector of making by steel wire rope 10 on the described casing 1, auxiliary security protector 10 has two free ends that connect motor and ceiling respectively, motor falls and causes injury or electric leakage to human body to cause fire in the time of can preventing that leg is installed to get loose, and has improved security of products.

Also be equipped with power line 9 on the described end cap 7, power line 9 is electrically connected with armature winding 2, and the power line of armature winding 29 extends into from front end housing, conveniently determines best electric fan mounting points, needn't be limited by the position of external power supply line interface.

Described end cap 7 is provided with the concave part 701 that can receive carbon dust 702, sliding contact position between concave part 701 corresponding commutators 6 and the brush 5, commutator 6 can be deposited on front end housing 7 recessed portions 701, the possibility that has reduced short circuit and entered bearing and rotating shaft contact position with the carbon dust 702 that brush 5 sliding contacts wearing and tearing produce

Structure of the present utility model is not limited to this ceiling fan with on the DC motor, also can be used in the structure of other all kinds of motors, and these simple adulteriums all fall within protection range of the present utility model.
