Description
Technical field
The utility model relates to a kind of two cooling compact variable-frequency motor, be specially adapted to European crane and lightweight bridge, gantry crane, suspended structure taked by motor and reductor, requires that motor is light and handy with the occasion reducing the impact to reductor and jack machinism as much as possible.
Background technology
Bridge crane and gantry crane are the maximum hoisting equipments of use amount, the traditional lifting mechanism of China adopts the driving pattern of several component combinations such as motor, brake, decelerator, reel, assembly pulley mostly, volume is large, quality is large, installation requirement is high, and European crane and lightweight crane generally adopt three fulcrum support installation approach, the unsettled installation of motor, claimed structure is compact, and volume is little, power is large, make jack machinism more light and handy, during operation, balance is better.
Summary of the invention
The purpose of this utility model is a kind of two cooling compact variable-frequency motor of design, meets the needs of European crane and lightweight crane.
The technical solution of the utility model is achieved like this: a kind of two cooling compact variable-frequency motor, comprise stator core, cast-aluminum rotor, armature spindle, axle stretch end flange end cap, non-shaft stretching end end cap, stator core inner vent, stator core separate ventilation hole, stator coil, axial flow blower, internal fan is contained on the armature spindle in axle stretch end flange end cap, and cast-aluminum rotor is provided with axial ventilation road.
Described axial ventilation road has 5 ~ 20, waits central angle to arrange along cast-aluminum rotor circumference.
The diameter in described axial ventilation road is the 6%-10% that motor center is high.
Described stator core is made up of the stator punching of inner circle foreign side, makes motor be square, does not establish support.
Advantage of the present utility model: motor of the present utility model is square, there is no special support, be made up of stator punching, not only effectively increase the real area of stator punching, and the heat that motor winding produces can directly be delivered in air by stator punching, radiating efficiency is very high.Motor has two cover aeration structures, a set of be mounted in motor afterbody forcing functions blower fan and stator punching on separate ventilation hole composition, the heat of the stator that can leave efficiently; Air duct on another set of internal fan by motor stator inside, cast-aluminum rotor and the inner vent on stator punching form, internal fan rotates with rotor axis of electric, can the heat of motor internal be stirred more even, heat is enable to quickly move through stator core and end cap distributes, because Rated motor rotating speed is generally more than 2000 revs/min, so efficiency is also very high.Because motor does not have support, effectively alleviate the weight of motor, make the electric machine structure of different capacity all closely.Its good Design of ventilation and compact structure design, significantly reduce electric machine temperature rise.
The feature of this motor is that structure is tightly gathered, volume is little, power is large, not only reduces the deadweight of crane, significantly reduces the height of crane simultaneously.
This motor does not have special support, is directly made up of stator core, and its length can adjust with power of motor, can ensure the electric machine structure of different capacity all closely, motor has two cover aeration structures, can dispel the heat efficiently, thus reduction electric machine temperature rise, increase the power density of motor.

Embodiment
As shown in Figure 1, two cooling compact variable-frequency motor centers height of the present embodiment is 100-355, comprise stator core 1, cast-aluminum rotor 2, armature spindle 3, axle stretch end flange end cap 4, non-shaft stretching end end cap 5, stator core inner vent 6, stator core separate ventilation hole 7, stator coil 8, axial flow blower 9, internal fan 11 is contained on the armature spindle 3 in axle stretch end flange end cap 4, and cast-aluminum rotor 2 is provided with axial ventilation road 12.10 is cast-aluminum rotor leaf blades, and 8a is stator coil end,
Fig. 2, Fig. 3 are the structural representations of stator core: stator core 1 is made up of the stator punching of inner circle foreign side, and make motor be square, motor stator does not have special support, is directly made up of stator core and motor winding.Stator core inner vent 6 and stator core separate ventilation hole 7 are distributed in both sides inside and outside seam 1a.
Fig. 4, Fig. 5 are the structural representations of cast-aluminum rotor: axial ventilation road 12 has 5 ~ 20, wait central angle to arrange along cast-aluminum rotor 2 circumference.The diameter in axial ventilation road 12 is the 6%-10% that motor center is high.
Axial flow blower 9 is contained in motor tail end, and wherein internal fan 11 rotates with rotor.Because stator coil 8 leading-out terminal end winding 8a is relatively long, so just utilize this space mounting internal fan 11, not only can take away the heat of rotor itself, the heat of motor internal can also be stirred, and by stator core and two ends end cap Quick diffusing.Non-leading-out terminal winding overhang is relatively short, just can hold the leaf blade 10 of cast-aluminum rotor self, axle stretch end flange end cap 4 and non-shaft stretching end end cap 5 be a cavity all, just contain part winding overhang 8a, make the structure of motor closely, and motor does not have support, the length of stator core 1 can adjust according to power of motor, makes the motor of different capacity can ensure the compactedness of structure.
Wind path A: formed by internal fan 11, stator core inner vent 7 to cast-aluminum rotor fan blade 10, cast-aluminum rotor ventilating channel 12.
Wind path B: formed by axial flow blower 10 and stator core separate ventilation hole 6.
Wind path A can make the heat of internal rotor relatively evenly and very fast being delivered on stator core 1 and two ends end cap 4,5, and stator core thermal conductivity is very high, and heat can be distributed by wind path B soon.The good circulation of wind path A and wind path B can reduce the temperature rise of motor effectively, and the structure of motor itself closely, and on the basis not increasing core length, performance improves, and overall dimensions reduce.
