Description

Motor rotor

Technical Field

The utility model belongs to the technical field of the motor accessories, in particular to electric motor rotor.

Background

The motor is used for realizing the conversion between electric energy and mechanical energy, and the main structure is a rotating shaft and superposed rotor punching sheets on the rotating shaft. In the prior art, dislocation occurs during installation, so that the product quality is reduced; when the rotor runs at high speed, a large amount of heat is generated, so that the service life is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a motor rotor, effectual above-mentioned problem of having solved to prior art's not enough.

The technical scheme of the utility model is realized like this: the utility model provides an electric motor rotor, includes pivot, insulator and rotor punching, the insulator cover establish the outside in pivot, the pivot punching have a plurality of, the outside at the insulator is established to the stack cover, the central point of pivot, insulator and rotor punching on same straight line, the periphery of rotor punching be equipped with align to grid's winding wire groove, the rotor punching in the middle of be equipped with the shaft hole, the shaft hole on be equipped with the breach, the insulator outside be equipped with the latch, latch and breach phase-match, the shaft hole edge be equipped with align to grid's louvre, the louvre side be equipped with the locating hole, locating hole below be equipped with down trapezoidal through-hole.

And further setting, the length of the inverted trapezoidal through hole is smaller than the thickness of the rotor punching sheet.

Further, a plurality of channels are arranged in the middle of the rotating shaft, and glue is filled in the channels.

Further, the insulator material is plastic.

Compared with the prior art, the beneficial effects of the utility model are that: the clamping teeth are matched with the notches, so that dislocation is avoided during installation; the positioning holes are arranged, so that the situation that the stamped sheets are staggered with each other is prevented; the setting of louvre firstly alleviates the weight of itself, dispels the heat to inside when two function.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to the attached drawing and show, a motor rotor, including pivot 1, insulator 2 and rotor punching 3, insulator 2 cover establish the outside at pivot 1, pivot 1 punching have a plurality of, the stack cover is established in the outside of insulator 2, pivot 1, insulator 2 and rotor punching 3 central point on same straight line, rotor punching 3 periphery be equipped with align to grid's winding wire groove 4, rotor punching 3 in the middle of be equipped with shaft hole 8, shaft hole 8 on be equipped with breach 6, insulator 2 outside be equipped with latch 5,

latch

5 and 6 phase-matchings, the direct breach 6 of latch 5 matches during the installation, be convenient for install, 8 edges in shaft hole be equipped with align to grid's louvre 7, reduce inside temperature when using, increase of service life. The side of the heat dissipation hole 7 is provided with a positioning hole 9, and an inverted trapezoidal through hole 10 is arranged below the positioning hole 9.

Further, the length of the inverted trapezoidal through hole 10 is smaller than the thickness of the rotor punching sheet 3, and the pin of the trapezoidal through hole is inserted into the positioning hole 9 of the next rotor punching sheet 3, so that the whole rotor punching sheet cannot be dislocated.

Further, a plurality of channels 11 are arranged in the middle of the rotating shaft 1, glue is filled in the channels 11, and the rotating shaft 1 and the insulator 2 are adhered more firmly.

Further, the insulator 2 is made of plastic.

It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
