Description
Technical field
The present invention relates to a kind of external rotor permanent magnet motorized pulleys, especially a kind of cooling outer rotor permanent-magnet motorized pulleys.
Background technology
It is well known that in the case where cylinder sizes are certain, the direct factor for influencing motor power (output) is exactly the hair of motor
Heat and heat dissipation think that promotion motor power (output) will be to the promotion of radiating condition.Currently, the cooling outer rotor permanent-magnet electricity of the prior art
Dynamic roller is casing water cooling, and this mode needs that radiator is added to control the generation of condensed water, is dissipated in use if forgetting to open
Hot device can cause to generate condensed water and lead to burning for coil.Water cooling casing, which is generally, welds water cooling casing, when after the completion of welding
The micro- infiltration phenomenon not being found, since the variation of hydraulic pressure causes leakage to be aggravated when longtime running, so as to cause the burning of coil
It ruins.Therefore, a kind of cooling outer rotor permanent-magnet motorized pulleys are designed, are the current technical issues that need to address.
Invention content
Technical problem to be solved by the invention is to provide a kind of external rotor permanent magnet motor.
The present invention the technical solution to solve the technical problem is that：
Cooling outer rotor permanent-magnet motorized pulleys, including stator, stator are formed by stacking by stator punching, are had on stator punching several
Equally distributed circulating water pipe through hole, it is logical in the circulating water pipe of stator punching by tube technique in circulating water pipe through hole
Straight tube pipe is set in via, one end of wherein one straight tube pipe is used as water inlet, by one end of another straight tube pipe with making
The port of adjacent straight tube pipe is welded together to form S-shaped cooling-water duct by the mouth of a river, the effective U-tube of remaining straight tube.
As a preferred embodiment of the present invention, the straight tube pipe is stainless-steel seamless pipe, and the U-tube is not
Rust steel seamless steel U-tube.
As a preferred embodiment of the present invention, entire stator utilize vacuum encapsulation epoxy resin, make one it is whole
Body.
As a preferred embodiment of the present invention, the diameter R of stator punching is 360mm, and the long L of iron core is 500mm, recirculated water
The diameter R of pipe through hole is 25mm, and the number of circulating water pipe through hole is 18.
Compared with prior art, the present invention has heat dissipation area big, will not seep water, and the entire stator winding of motor utilizes
Vacuum encapsulation epoxy resin makes an entirety, improves winding overall mechanical strength and waterproof and dustproof, anti-fouling effect
Significantly.Winding after embedding has good insulation and corona-resistance property, motor turn-to-turn caused by effectively solving inverter supply
Short circuit problem greatly improves the insulated aging life-span of variable-frequency motor.The epoxy resin of special proportioning has good heat conductivility,
The heat conductivility of winding overhang after embedding greatly improves, and effectively reduces the Wen Sheng of stator winding end.Epoxy resin is whole
Embedding, impact resistance, anti-vibration, humidity resistance is good, and stator heater need not be configured in use.Stator vacuum pouring dosing technology
Improvement motor can be made to be used safely under the adverse circumstances such as high temperature, low temperature, vibration, dust, humidity, burn into load shock.
Cooling water pipe by making an entirety inside resin embedding to stator core.Motor is set not to be afraid of in use
Generate condensed water.Also stator heater is not being needed in the generation for being afraid of that cooling water pipe has leakage.
Below by taking long L=500 of the iron cores of circular diameter R=360 in stator punching as an example, the present invention is illustrated by example calculation
The hot area S2 of combustion and the prior art heat dissipation area S2 difference：
The mm2 of S1=R × π × L=565486,
The mm2 of S2=R × π × L × 16=706858,
S2 ＞ S1,
1.25 times of effect original structure under identical water flow.
