Summary of the invention
Technical problem to be solved by this invention is to provide a kind of motor silicon steel sheet, the problem that copper factor is low, rule is loaded down with trivial details, mass of coil is unstable, finished product motor slot is large and motor performance is poor that it can solve conventional motor.
For solving the problems of the technologies described above, motor of the present invention by the technical solution of silicon steel sheet is:
Comprise integrated silicon steel sheet body, silicon steel sheet body is the annular with thickness, and silicon steel sheet body is along being circumferentially distributed with multiple utmost point grooves, and utmost point groove is along the radially extension of silicon steel sheet body; One end of utmost point groove is provided with opening, utmost point groove is connected with the inner edge of silicon steel sheet body, or is connected with the outer rim of silicon steel sheet body; Utmost point groove is for accommodating coil; The inner edge of silicon steel sheet body or outer rim are provided with multiple cramps; Cramp is along the circumferential extension of silicon steel sheet body, and multiple cramps form a circle; The two ends of each cramp are respectively arranged with notch, and the notch of adjacent cramp matches; Cramp is radially fixedly connected with silicon steel sheet body; Between adjacent cramp, form coiling gap; Described coiling gap is connected with utmost point groove.
The inwall of described utmost point groove is equipped with insulating paper; Or the inner-wall spraying of utmost point groove has insulating barrier.
The side of described cramp is provided with dovetail groove, and the inner edge of described silicon steel sheet body or outer rim are provided with the swallow-tail form projection matching with the dovetail groove of cramp; The side of cramp is fixedly connected with silicon steel sheet body by dovetail structure.
The end face of described cramp is provided with rivet; Rivet extends along the thickness direction of cramp, and the one side of rivet is projection, and another side is the pit matching with projection.
The end face of described cramp arranges through hole.The technique effect that the present invention can reach is:
Rule notch of the present invention greatly, easily roll off the production line.
The present invention can realize detachably, and coil directly requires single line to carry out coiling according to power of motor, has solved many lines and around the problem that easily occurs turn-to-turn short circuit.
The number of turn of coil of the present invention and arrangement understand large small-scale production efficiency is had to the change of matter in good order.
It is very little that the present invention can make notch accomplish as requested, just can greatly improve motor performance this parameter, also improved the performance of motor simultaneously other parameters.

Embodiment
As shown in Figure 1 and Figure 2, motor silicon steel sheet of the present invention, comprises integrated silicon steel sheet body 1, and silicon steel sheet body 1 is for having certain thickness annular, and silicon steel sheet body 1 is along being circumferentially distributed with multiple utmost point grooves 2, and utmost point groove 2 is along the radially extension of silicon steel sheet body 1; One end of utmost point groove 2 is provided with opening, utmost point groove 2 is connected with the inner edge of silicon steel sheet body 1, or is connected with the outer rim of silicon steel sheet body 1;
Utmost point groove 2 is for accommodating single line coil 4;
The inwall of utmost point groove 2 is equipped with insulating paper 3, or has insulating barrier at the inner-wall spraying of utmost point groove 2;
The inner edge of silicon steel sheet body 1 or outer rim are provided with multiple cramps 6; Cramp 6 is along the circumferential extension of silicon steel sheet body 1, and multiple cramps 6 form a circle; As shown in Figure 3, the two ends of each cramp 6 are respectively arranged with notch 5, and the notch 5 of adjacent cramp 6 matches;
Cramp 6 is radially fixedly connected with silicon steel sheet body 1; Between adjacent cramp 6, form coiling gap; Coiling gap is connected with utmost point groove 2;
The side of cramp 6 is provided with dovetail groove, and the inner edge of silicon steel sheet body 1 or outer rim are provided with the swallow-tail form projection matching with the dovetail groove of cramp 6; The side of cramp 6 is fixedly connected with silicon steel sheet body 1 by dovetail structure;
