Abstract
The utility model belongs to motor field and provides a stator and an electromotor. The stator comprises a stator core and multiple windings. An insulating wrapping layer is formed on the periphery of the stator core through injection molding technology. The windings are wounded around the wrapping layer and are wound together to form a leading-out neutral line. An installation fixing groove is disposed on the wrapping layer. The neutral line is installed and fixed in the installation fixing groove. The electromotor comprises the above stator and a rotor adaptive to the stator. The stator and the electromotor are capable of effectively preventing the neutral line of the stator windings form being dispersed when injection molding is performed, and achieving tidy winding wiring.

Further, described stator also comprises flexible pipe, and the described neutral line is placed in described flexible pipe and by described flexible pipe and is fastened between described trapezoid boss.
Preferably, described flexible pipe is the silica gel glass fiber hose.
Further, described the first convex tendon is provided with three for first otch of described winding in entering described installation holddown groove.
Further, also be provided with at least one on described the second convex tendon for reducing the second otch of described the second convex tendon intensity.
Further, on described the second convex tendon, the position corresponding with described trapezoid boss is provided with the square through hole of withdrawing pattern after convenient described trapezoid boss moulding.
Compared with prior art, the beneficial effect of the stator that the utility model provides is: the covered plastics layer of the utility model stator is provided with for the three-phase neutral line of winding fixing installation holddown groove is installed, this installs holddown groove can prevent effectively that the three phase winding neutral lines from being broken up out when injection moulding, also can make winding wiring more neat.
Three of the purpose of this utility model is to provide a kind of motor, and described motor comprises above-mentioned stator and the rotor adaptive with this stator.
Compared with prior art, the beneficial effect of the motor that the utility model provides is: owing to having adopted said stator, in the utility model motor, stator core and winding are kept apart by covered plastics layer, the installation holddown groove of covered plastics layer setting is fixed on the neutral line of winding in it, prevented that effectively the neutral line from being broken up out when injection moulding, also made the winding wiring of motor more neat.
