Abstract
The utility model provides a submerged explosion-proof permanent-magnet brushless DC motor, which belongs to the technical field of motors, and particularly relates to a low-power large-torque high-efficiency submerged low-tension explosion-proof permanent-magnet brushless DC motor. The main technical characteristics are that a stator is pressed into a casing; a steel magnet rotor is mounted on a shaft; a snap ring is mounted at the driving end of the rotor; a first bearing and a second bearing are mounted at the positioning parts at two ends of the shaft; a first end cover is mounted at the non driving end of the casing, and a first seal ring is mounted between the first end cover and the casing; a shaft seal is mounted into a shaft hole of a second end cover; the second end cover is mounted at the driving end of the casing, and a second seal ring is mounted between the second end cover and the casing; and an anti-drag cover is mounted on the outer side of the first end cover. The DC motor provided by the utility model can be used underground in coal mines, satisfies the explosion-proof and waterproof requirements, has high mechanical strength, corrosion resistance and small size, and is convenient to maintain.
Description
Technical field
The utility model belongs to the motor technology field, particularly a kind of explosion-proof permanent-magnet brushless DC motor of small-power large torque and high-efficient rate diving low-voltage.
Background technology
The permanent magnet DC brushless motor of low capacity is widely used in many industries such as electric power, machinery, oil, chemical industry, traffic, urban water supply at present, and technology is very ripe.But the permanent magnet DC brushless motor of middle low capacity also is not applied under the coal mine, more of no use in danger, in the explosive gaseous environment under water, its reason because traditional DC motor all belongs to non-explosion-proof type, is used aluminium alloy on the one hand often, and materials such as aluminium are done motor housing, do not possess in the adverse circumstances of down-hole and use, secondly, in the water under the dangerous explosive environments, use, must make motor flame proof, water resistance fabulous; Therefore present permanent magnet DC brushless motor does not possess the service condition under water in dangerous explosive environments.
The utility model content
The purpose of this utility model provides a kind of can the use under coal mine, reach the diving flame proof brushless, permanently excited direct current motor of flame proof, waterproof requirement.
The technical scheme that the utility model is taked is: diving flame proof brushless, permanently excited direct current motor, comprise drag reduction lid, first end cap, second end cap, casing, stator, magnet steel rotor, shaft seal and axle, press-fit stator in the casing, the magnet steel rotor is installed on axle, rotor shaft extension end is installed snap ring, clutch shaft bearing, second bearing are installed by place, location, two ends at axle, and first end cap is installed in non-shaft extension one end of casing, and first sealing ring is installed between first end cap and the casing; The shaft seal of in the second end cap axis hole, packing into, second end cap is installed in casing shaft extension end, and second sealing ring is installed between second end cap and the casing, and the drag reduction lid is installed in first end cap outside.
The utility model diving flame proof brushless, permanently excited direct current motor is compared with the prior art motor, have waterproof, flame proof, high-efficiency characteristics, owing to adopt the stainless steel casing, electromechanics intensity height, corrosion-resistant, volume is little, easy to maintenance, can in the equipment of the big torque of small-power, substitute traditional flame-proof electric motor of existing heaviness, highly energy-consuming.
Description of drawings
Fig. 1 is the main diagrammatic sketch of the utility model diving flame proof brushless, permanently excited direct current motor;
Fig. 2 is the cross-sectional view of Fig. 1.
Embodiment
The utility model diving flame proof brushless, permanently excited direct current motor as shown in Figure 1 and Figure 2, comprise drag reduction lid 1, first end cap 2, second end cap 11, casing 5, stator 6, magnet steel rotor 7, shaft seal 12 and axle, press-fit stator 6 in the casing 5, magnet steel rotor 7 is installed on axle 13, rotor shaft extension end is installed snap ring 8, clutch shaft bearing 3 is installed at place, location, two ends at axle, second bearing, 9, the first end caps 2 are installed in casing 5 non-shaft extension one ends, and first sealing ring 4 is installed between first end cap 2 and the casing 5; Shaft seal 12, the second end caps 11 of packing in second end cap, 11 axis holes are installed in casing 5 shaft extension ends, and second sealing ring 10 is installed between second end cap 11 and the casing 5, and drag reduction lid 1 is installed in first end cap, 2 outsides.
The technical scheme that the utility model is taked is improved to produce on the basis of original common permanent magnet DC brushless motor, the sheathing material of common electric machine is changed into stainless steel material, increase motor drag reduction lid, strengthen the intensity of electric machine casing, between bearing and the end cap, add the waterproof sealing design between casing and end cap, anti-sealing infiltrates.Anti-explosion cable is all adopted in the wiring of power line and Hall element, and wire cavity all adopts the explosion-proof waterproof seal that adds.
