Abstract
The invention discloses an inner stator punching sheet of a motor, which comprises a circular punching sheet body and is characterized in that two arc-shaped grooves are symmetrically arranged at the periphery of the punching sheet body; the circle centers of the two arc-shaped grooves and the circle centers of the punching sheet body are in the same straight line; a semi-circular groove is arranged beside each arc-shaped groove; and the radius of the semi-circular groove is 2.5-3.5mm. In the inner stator punching sheet, two notches which are the arc-shaped groove and the semi-circular groove are arranged at the periphery of the punching sheet body, wherein the radius of the semi-circular groove is 3mm; and after practice, the currents of a motor are more stable, the heat dispersion performance is good, and the service life is prolonged.
Description
Technical field
The present invention relates to motor stator, particularly a kind of electric motor internal stator punching.
Background technology
Motor stator is to be made of coil and stator core, and stator core is to be formed by the direction accumulation of a plurality of stator punchings along axle, during machine operation, produces a large amount of heats, directly has influence on the operating efficiency of motor.
For this reason, on the neighboring of stator punching, offer deep-slotted chip breaker,, be beneficial to the heat radiation of motor to form the heat radiation gap.
But the groove that plays thermolysis on the stator punching is many more, and big more radiating effect is just good more, and still, the groove that plays thermolysis on the stator punching is many more or big more, and the magnetic field degree of saturation of motor is just serious more, and efficiency of motor is also just low more.
So how reasonably shape, the number to the groove on the stator punching designs, make it can either efficiently radiates heat, can improve efficiency of motor again, make the electric current of motor more stable, become a urgent problem.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, and a kind of internal stator punching that can either dispel the heat and can improve motor working efficiency motor is provided.
Technical scheme of the present invention is achieved in that
A kind of electric motor internal stator punching, comprise circular punching body, it is characterized in that: on the periphery of punching body, be arranged with two deep-slotted chip breakers, the center of circle of the center of circle of two deep-slotted chip breakers and punching body is on same the straight line, also be provided with a semi-circular groove on each deep-slotted chip breaker side, the radius of described semi-circular groove is 2.5～3.5mm.
As preferably, the radius of described semi-circular groove is 3mm.
As preferably, on the periphery of punching body, also be arranged with two external stator contact webs, on external stator contact disc limit, be provided with in order to the short circuit annular groove of short-circuited conducting sleeve to be installed, the width of short circuit annular groove is 2.5～3.5mm, the length of short circuit annular groove is 9～12mm.Equally, the present invention designs the length and width of short circuit annular groove, and electric motor starting speed is accelerated, and has improved motor properties.
As preferably, the width of short circuit annular groove is 3mm, and the length of short circuit annular groove is 9mm.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention is provided with two notches on the periphery of punching body, one is deep-slotted chip breaker, and one is semi-circular groove, and the radius of semi-circular groove is 3mm, and through practice, current of electric is more stable, and heat dispersion is good, has also obtained prolongation useful life.
Description of drawings
Fig. 1 is the structural representation of internal stator punching of the present invention.
Embodiment
The specific embodiment of the present invention is as follows:
