Outside forging shaft serpentine groove, serpentine water-cooling channel is internally formed in motor shaft, stator is installed on described shaft sleeve, it is described
Stator inside and outside teeth groove in be wrapped the Circular Winding of motor, it is inside and outside that described Circular Winding is wrapped in stator per circle coil
Close in portion's teeth groove and by stator yoke back, rotor is installed outside described stator, is had between described rotor and stator
Air gap, is equipped with sleeve, skid resistant course is cased with sleeve outer wall outside described rotor.
The described outer rotor Circular Winding induction machine with water-cooling, the shaft sleeve two ends that described forging shaft is socketed
End sealing ring A and end sealing ring B is separately installed with, described motor shaft ends have two paddle holes, described paddle hole
Outside is connected with confession, drainage arrangement, and in described motor shaft, measuring tool has the wire hole for laying extracting power supply cord, described stator tool
There are internal tooth and external tooth, described internal tooth quantity is identical with described external tooth quantity.
The beneficial effects of the utility model：
1st, induction machine of the present utility model, using Novel electric arbor, by taking idle call blower fan as an example, makes relative to traditional
For the outer rotor induction machine of cydariform winding, its using Circular Winding copper cash amount be original 80%, copper cash usage amount
It is greatly decreased and improves efficiency.
, induction machine of the present utility model, using the motor shaft of water-cooling structure, due to the specific heat capacity of water it is big, relative to not having
There are cooling or air cooled motor shaft, motor internal temperature can be greatly lowered, and on the basis of structural strength is ensured,
Heat can be taken away with machine winding directly contact using special motor shaft structure so that radiating effect is more projected, in electricity
Higher electromagnetic load and thermic load are can select in the design of machine, the efficiency of motor is improve, reduce motor volume and
Motor service life and reliability of operation can also be improved, economic effect is obvious.
, induction machine of the present utility model, using Circular Winding, breach relative to the winding Circular Winding of traditional form
The concept of pitch on traditional winding configuration, can more flexibly realize the pole-changing in the case of unregulated power electronic device.
, induction machine of the present utility model, copper factor can be greatly improved without layer insulation relative to traditional induction machine
And offline convenience, the copper factor in stator slot in described Circular Winding induction conductivity is 85%-90%.
