Description
Technical field
The utility model relates to a kind of external rotor permanent magnet motorized roller, especially a kind of electronic rolling of cooling outer rotor permanent-magnet
Cylinder.
Background technique
It is well known that the direct factor for influencing motor power (output) is exactly the hair of motor in the case where cylinder sizes are certain
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 plus radiator controls the generation of condensed water, is dissipated in use if forgetting to open
Hot device will lead to and 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 roller is designed, is the current technical issues that need to address.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of external rotor permanent magnet motor.
The technical scheme in the invention for solving the technical problem is:
Cooling outer rotor permanent-magnet motorized roller, including stator, stator are formed by stacking by stator punching, are had on stator punching
Several equally distributed circulating water pipe through holes pass through tube technique in the recirculated water of stator punching in circulating water pipe through hole
Straight tube pipe is set in pipe through hole, one end of a wherein straight tube pipe is used as water inlet, one end of another straight tube pipe is used
Make water outlet, the port of adjacent straight tube pipe is welded together to form S-shaped cooling-water duct by the effective U-tube of remaining straight tube.
As a kind of preferred embodiment of the utility model, the straight tube pipe is stainless-steel seamless pipe, the U-tube
For stainless steel jointless steel U-tube.
As a kind of preferred embodiment of the utility model, entire stator utilizes vacuum encapsulation epoxy resin, makes one
A entirety.
As a kind of preferred embodiment of the utility model, the diameter R of stator punching is 360mm, and the long L of iron core is 500mm, is followed
The diameter R of ring water pipe through hole is 25mm, and the number of circulating water pipe through hole is 18.
Compared with prior art, the utility model has heat dissipation area big, will not seep water, and the entire stator winding of motor
Using vacuum encapsulation epoxy resin, an entirety is made, improves winding overall mechanical strength and waterproof and dustproof, antifouling
Significant effect.Winding after encapsulating has good insulation and corona-resistance property, effectively solves motor caused by inverter supply
Turn-to-turn short circuit problem greatly improves the insulated aging life-span of variable-frequency motor.The epoxy resin of special proportion has good thermally conductive
The heating conduction of performance, the winding overhang after encapsulating greatly improves, and effectively reduces the temperature rise of stator winding end.Epoxy resin
Whole encapsulating, impact resistance, anti-vibration, humidity resistance is good, and configuration stator heater is not needed in use.Stator vacuum pouring encapsulating
The improvement of technique can make motor safety under the adverse circumstances such as high temperature, low temperature, vibration, dust, humidity, burn into load shock
It uses.Cooling water pipe by making an entirety inside resin encapsulating to stator core.Make motor in use
Be not afraid of to 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 core of circular diameter R=360 in stator punching as an example, illustrate that this is practical by example calculation
The difference of the heat dissipation area S2 of novel combustion heat area S2 and the prior art:
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.
