Abstract
The utility model relates to an electric machine stator winding structure, it includes inslot coil, end coil, the in situ is insulating fills up, middle part axial between the layer of inslot coil is equipped with insulating pad of in situ and becomes two parts with one deck coil isolation. The utility model discloses because the middle part sets up insulating pad of the reliable in situ of insulating properties between the layer of inslot coil, become two parts with coil isolation, greatly reduced the possibility that punctures of inslot coil turn to turn, this kind of structural style's insulating properties is reliable, has improved the security performance of motor operation. The utility model discloses still include a motor that contains this kind of motor stator winding construction.
Description
Technical field
The utility model belongs to field of motor manufacturing, relates in particular to a kind of motor stator winding structure and motor.
Background technology
At present, for the motor stator winding of loose embedded, its stator winding embedded coil is only provided with laminated insulation, in end by coil overall binding, for the motor stator winding of the higher loose embedded of voltage, the insulating properties of the laminated insulation in slot for winding are limited, and therefore the possibility of this version generation breakdown between adjacent turns is very large, insulating properties are poor, affect the safety of motor operation.
Utility model content
The purpose of this utility model is to overcome above defect, and the reliable motor stator winding structure of a kind of insulating properties and motor are provided.
The technical solution of the utility model is: a kind of motor stator winding structure, and it comprises embedded coil and end coil, also comprises a layer interior felt pad, the middle part of the interlayer of described embedded coil is axially arranged with layer interior felt pad one deck inductance loop seclusion is become to two parts.
Preferably, the interior felt pad of described layer is arranged on 1/2nd places at embedded coil middle part.
Preferably, every circle coil of described end coil is independently wrapped up.
Preferably, in described layer, felt pad material is compound folder 6050 Kaptons of NHN.
The utility model also provides a kind of motor, and it comprises motor stator winding structure, and described motor stator winding structure is motor stator winding structure described above.
Useful technique effect of the present utility model is, due to felt pad in the interlayer middle part of embedded coil arranges the reliable layer of insulating properties, inductance loop seclusion is become to two parts, greatly reduce the possibility of embedded coil breakdown between adjacent turns, further the every circle coil of end coil is independently wrapped up, greatly reduce the possibility of end coil breakdown between adjacent turns, the insulating properties of this version are reliable, improved the security performance of motor operation.
