Abstract
The invention discloses a series motor water-cooling structure comprising a motor rotor, a stator, a commutator, and a cooling pipe. The cooing pipe is mainly composed of two mutually-communicated parts, namely, a part near the outer surface of the commutator and a part adhered to the outer surface of the stator. A water inlet and a water outlet of the cooling pipe are respectively disposed at the two sides of a motor shell. By adopting the device, the size of a fan is reduced, the air volume is reduced, the defect of motor air-cooling is overcome, a series motor can be cooled effectively, and a high-power series motor is made possible.
Description
Technical field
The present invention relates to motor cooling technology field, especially a kind of series excited machine water-cooling structure.
Background technology
Current motor cooling mainly air-cooled structure, namely fan is equipped with in rotor front end, fan rotates and produces air-flow, the air-flow produced enters in motor by the air inlet on casing, distinguished and admirable air gap between stators and rotators, then flow out from the air outlet of casing lower end, take away heat, thus air cooling is carried out to rotor.The shortcoming of this structure is:
The first, invisible waste is larger.
The second, can only by the distinguished and admirable heat taking away rotor surface, cooling effect is poor.
3rd, motor noise is comparatively large, and fan is larger, and distinguished and admirable larger, cooling effect is better, but the noise that fan produces is also larger, and the distinguished and admirable vibration produced through motor internal is also larger.
The another kind of type of cooling of motor is water-cooled, namely cooling water pipe is set in motor casing inside, cooling water pipe coils the internal circular surfaces in the external circular surfaces of motor or motor casing overcoat, form spirality cooling-water duct, water inlet and delivery port lay respectively at the two ends of motor, and cooling water enters from water inlet, whole casing is flowed through along spiral channel, flow out from the delivery port of the motor other end again, take away heat, be embodied as the object of electric motor temperature reduction.But cooling water is by the needs regular hour in whole spiral channel, and therefore cooling-down effect is not ideal.And this simple spiral water passage is also not suitable for series excited machine, because there are commutator and brush in the top of series excited machine, due to the existence of brush, cooling water pipe cannot outside steering gear coiled coil, thus cannot lower the temperature for commutator, and then affect the cooling effect of whole motor.Just because of the effective type of cooling of shortage, existing series excited machine power is generally little.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of water-cooling structure of series excited machine, can reduce fan after applying this device, reduce air quantity, thus overcome the air-cooled defect of motor, simultaneously effective cooling series excited machine, and making to make high-power series excited machine becomes possibility.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of series excited machine water-cooling structure, comprise the rotor of motor, stator, commutator and cooling water pipe, described cooling water pipe primarily of near commutator outer surface with docile in stator outer surface, two parts of interconnecting form, the water inlet of cooling water pipe and delivery port lay respectively at the both sides of motor casing.
Further improvement of the present invention is: be positioned at the back-shaped structure that cooling water pipe on stator and the cooling water pipe be positioned on commutator are all set to the roundabout arrangement of axis along stator and commutator.
Further improvement of the present invention is: back-shaped cooling water pipe is two pieces, is relatively arranged on the side of the stator perpendicular with the line of two brushes and commutator.
Further improvement of the present invention is: described cooling water pipe is set to helical structure at stator outer surface, and two sides perpendicular at the line of commutator and two brushes arrange two back-shaped structures.
Further improvement of the present invention is that between cooling water pipe on commutator and the cooling water pipe on stator, rounding off connects.
Further improvement of the present invention is: be provided with fan in the end of rotor.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
The present invention combines with air cooling way, and be effectively series excited machine cooling, making to make high-power series excited machine becomes possibility.
Because of series excited machine operate time, pyrotoxin is the parts such as line bag, commutator and brush, the present invention is provided with cooling water pipe at stator outer surface and commutator outer surface simultaneously, directly heat can be taken away by water circulation, set up cold conditions environment by constantly passing into cooling water simultaneously, the distinguished and admirable energy formed by the rotation of rotor front end fan is more effective takes away heat, thus reaches the object of effective cooling series excited machine.
The cooling water pipe of the laundry in the present invention is close to stator surface, and the cooling water pipe at commutator place is near commutator face but be not in contact with it, so not only by cooling water take away commutator 4 place heat but also avoid in commutator rotation process with cooling water pipe frictional heat.
Cooling water pipe in the present invention on commutator and rounding off connection between the cooling water pipe on stator, cooling water is flowed in cooling water pipe more smooth and easy, cooling effect is better.
The position that cooling water pipe at commutator place in the present invention is arranged avoids cooling water pipe and interferes brush, does not affect motor and normally work while cooling motor.
The present invention increases water-cooling structure on air-cooled basis, therefore suitably can reduce fan, reduces air quantity, thus overcomes the shortcoming that former air-cooled invisible waste is large, vibration is large, noise is large.
