Abstract
The utility model 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 arranged at the periphery of the punching sheet body symmetrically, the circle centers of the two arc-shaped grooves and the circle center of the punching sheet body are arranged on the same line, a semi-circle groove is arranged beside each arc-shaped groove, and the radius of the semi-circle groove is 2.5-3.5mm. Two notches are arranged at the periphery of the punching sheet body, one notch is an arc-shaped groove, the other notch is a semi-circular groove, the radius of the semi-circular groove is 3mm, after practice, the current of the motor is more stable, the radiating performance is good, and the service life is prolonged.
Description
Technical field
The utility model relates to motor stator, particularly a kind of electric motor internal stator punching.
Background technology
Motor stator is to be made up 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 great amount of heat, 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 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.
The utility model content
The utility model has overcome the deficiency that exists in the above-mentioned prior art, and a kind of internal stator punching that can either dispel the heat and can improve motor working efficiency motor is provided.
The technical scheme of the utility model 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 is provided with a semi-circular groove on each deep-slotted chip breaker side, and 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 utility model 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 beneficial effect of the utility model of technique scheme to be:
The utility model 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 the utility model internal stator punching.
Embodiment
The embodiment of the utility model is following:
