Abstract
Disclosed is a compact three-phase asynchronous motor, belonging to the technical field of motors and in particular to a motor cooling system. The compact three-phase asynchronous motor is mainly technically characterized in that a cooling device adopts air and water composite cooling mode; a cooling system comprises an internal circulating air channel and a water circulating channel; a water jacket consisting of an inner water jacket and an outer water jacket wraps a stator core of the motor; a water passage which can be a radial spiral water passage or an axial circulating water passage is arranged between the inner water jacket and the outer water jacket; a water inlet is arranged at one end of the water passage and a water outlet is arranged at the other end of the water passage; a cooling water drain passage is arranged right below the motor and is connected with the water passage; an air cooling channel is arranged between the outer water jacket and an outer shell of the motor; and an air inlet and an air outlet are arranged at two ends of the air cooling channel. The asynchronous motor is small in volume, low in fabricating cost and good in heat dissipation effect, with the power increased by more than 2 times as compared with the other motors with the same volume.
Description
Technical field
The utility model belongs to the motor technology field, particularly motor cooling system.
Technical background
Existing motor cooling mode has air cooling, water-cooled, empty water mixing cooling etc. multiple, but the cooling device volume is big, causes the motor volume huge, and required installing space is big, and cooling effect is poor; Existing air water cooling is motor but, and motor and cooler are two independent bodies, and cooler places the motor top, and volume is big, manufacturing cost is high; The water-cooling apparatus of existing motor does not have cooling air channel, only relies on the heat conduction cool motors stator outside, and cooling effect is poor, and no-cooling-water drains passage, has influenced motor and has used for a long time, deposits and safeguard, has shortened the useful life of motor.
The utility model content
The utility model provides a kind of compact threephase asynchronous, has reduced volume, has reduced manufacturing cost, has improved radiating effect, has prolonged the useful life of motor.
The technical solution of the utility model is: motor comprises stator, rotor, cooling device and shell, cooling device adopts the compound cooling of empty water, circulation wind path and water circulation channel in comprising, water jacket is coated on outside the stator core in motor, is made of inner water sleeve and outer water jacket, and the centre is provided with water channel, water channel can be spiral channel radially or axial reciprocal water channel, the two ends of water channel are provided with water inlet and delivery port, and cooling water drains passage under motor, link to each other with water channel; Be cooling air channel between outer water jacket and motor casing, the cooling air channel two ends are provided with air inlet and air outlet.
Compare with background technology, the utility model compact three-dimensional asynchronous motor is owing to adopt empty water composite cooling apparatus, and volume is little, and is cheap for manufacturing cost.The motor interior film-cooled heat increases 1.5-2 doubly, and radiating effect obviously improves, and increases more than 2 times than other motor power (output) of same volume.Because the bottom of inner water sleeve is provided with cooling water and drains passage, be convenient to waste water and discharge, prolonged the useful life of motor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side diagrammatic sketch of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the compact threephase asynchronous comprises stator 3, rotor 6, cooling device and shell 4.Cooling device adopts the compound cooling of empty water, circulation wind path and water circulation channel in cooling device comprises; Water jacket is coated on outside the stator core in motor 3, constitute by inner water sleeve 7 and outer water jacket 5, the centre is provided with water channel 14, water channel can be spiral channel radially or axial reciprocal water channel, the two ends of water channel are provided with water inlet 2 and delivery port 8, cooling water drains passage 11 under motor, links to each other with water channel 14; 4 on outer water jacket 5 and shell are cooling air channels 13.
Interior circulated air route fan 10, air inlet 9, cooling air channel 13, air outlet 1 and rotor ventilation hole 12 are formed.
Water circulation channel is made up of water filling port 2, water channel 14 and delivery port 8.
The heat part that motor interior produces is passed through cross-ventilation, cooling air channel with heat through outside water jacket conduct to cooling water, dispel the heat to the motor space outerpace by motor casing simultaneously, heat on another part stator is by heat conducting form, conducted to cooling water through inner water sleeve by the motor stator sub-surface, cooling water conducts heat to outside the motor.During motor work, according to the cooling requirement, the water filling port injection pressure is the cooling water of 0.5-3Mpa, and cooling water is discharged from delivery port after absorbing heat by water channel.When motor maintenance or long-term storage, drain passage from the bottom cooling water and discharge waste water and impurity in the water jacket.
