Abstract
The utility model discloses an insulating iron core of a motor stator, wherein insulating layers are closed on the two end surfaces (1) of a main body of the stator iron core and the inner wall of a groove (2). The insulating iron core of a motor stator disclosed by the utility model prevents slot insulation and slot seal from being 7 mm higher than the two sides of the end parts of the iron core during the adoption of the slot insulation and the slot seal for insulating treatment for the motor stator, so as to greatly reduce the diameter of a winding coil, thus greatly reducing the usage of copper, and achieving a purpose of saving money. Because the diameter of the winding coil is greatly reduced, and the effective length of a winding in the iron core slot is invariable, so that the leakage reactance of the end part of the motor is reduced, and the efficiency of the motor can be greatly increased.
Description
Technical field
The utility model relates to the stationary part of motor, is specifically related to the structure of motor stator core insulation, promptly a kind of motor stator insulated iron core.
Background technology
The conventional motors stator insulation all adopts slot liner and groove envelope to carry out insulation processing when handling; When slot liner and groove envelope are adopted in motor stator insulated processing; Slot liner and groove envelope exceed core ends both sides 7mm, make the motor copper consumption increase, because the increase of winding coil diameter; And the effective length of winding in iron core slot is constant, thereby the raising that makes the end leakage reactance of motor increase electric efficiency is restricted.
Summary of the invention
The utility model technical problem to be solved provides a kind of insulation stator iron core, and to improve the insulation property reliability of motor stator, economical with materials significantly improves electric efficiency.
For realizing above-mentioned purpose, the utility model provides a kind of motor stator insulated iron core, is closed with insulating barrier on two end faces (1) of said stator core main body and the inwall of groove (2).
Said insulating barrier is the electrostatic spraying layer.
When the utility model had avoided motor stator insulated processing to adopt slot liner and groove envelope, slot liner and groove envelope exceeded core ends both sides 7mm, make reducing greatly of winding coil diameter, thereby significantly reduce copper consumption, reach the purpose of robbing.Because the reducing greatly of winding coil diameter, and the effective length of winding in iron core slot is constant, thereby makes the end leakage reactance of motor reduce, can significantly the improving of electric efficiency.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the right view of Fig. 1.
Below in conjunction with Figure of description utility model is done further to disclose.
Embodiment
Embodiment 1: as shown in Figure 1, motor stator comprises iron core, is added with insulating barrier on the inwall 2 of two end faces 1 of this iron core main body, the groove of stator body, thereby reaches the purpose that makes electric machine iron core and armature winding mutually insulated.
Embodiment 2: as shown in Figure 1, motor stator comprises iron core, is coated with the electrostatic spraying insulating barrier on the inwall 2 of two end faces 1 of this iron core main body, the groove of stator body, thereby reaches the purpose that makes electric machine iron core and armature winding mutually insulated.
Above-mentioned motor stator insulated processing is inappropriate for the inside and outside wall of stator core.
After the inwall that the utility model has the advantages that this motor stator end face, groove carries out insulation processing with electrostatic spraying or the method that adds insulating barrier; When having avoided motor stator insulated processing to adopt slot liner and groove envelope; Slot liner and groove envelope exceed core ends both sides 7mm; Make reducing greatly of winding coil diameter, thereby significantly reduce copper consumption, reach the purpose of robbing.Because the reducing greatly of winding coil diameter, and the effective length of winding in iron core slot is constant, thereby makes the end leakage reactance of motor reduce, can significantly the improving of electric efficiency.
Claims (2)
1. a motor stator insulated iron core is characterized in that: be closed with insulating barrier on two end faces (1) of said stator core main body and the inwall of groove (2).
2. a kind of motor stator insulated iron core according to claim 1 is characterized in that: said insulating barrier is the electrostatic spraying layer.
