Abstract
The utility model relates to an iron core punching sheet structure of a superspeed PMSM; the structure comprises a punching sheet body uniformly provided with a plurality of coil grooves; an opening port of the coil groove is provided with a block; and the length of the block is equal to the half of the width of the opening port of the coil groove. The iron core punching sheet structure is simple in structure and easy in processing; suitable slot wedges are employed to assemble the iron core, so air gap magnetic field of a stator and a rotor are uniformly distributed, thereby reducing harmonic waves generated by stator notches, reducing eddy current loss, reducing temperature rise of the motor, and improving running performance and service life of the motor.
Description
Technical field
The utility model belongs to machine field, relates in particular to a kind of ultrahigh speed permagnetic synchronous motor iron-core lamination structure.
Background technology
When conductor moved in non-uniform magnetic-field, the energy loss that the electric current of inducting in the conductor causes was called eddy current loss.
Motor is behind the stator core fluting, the air-gap field of rotor distributes no longer even, and the ultrahigh speed permagnetic synchronous motor is higher because of its frequency, the harmonic wave that stator rabbet is produced increases, the utmost point is more prone to produce eddy current loss on the rotor, it is large to cause that the motor feels hot, temperature rise, thereby to the runnability of motor with produce harmful effect useful life.
The utility model content
Based on this, for above-mentioned technical problem, provide a kind of ultrahigh speed permagnetic synchronous motor iron-core lamination structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of ultrahigh speed permagnetic synchronous motor iron-core lamination structure comprises the punching body, evenly offers a plurality of coil grooves on the described punching body, and the opening part of described coil groove is provided with a block, and the length of described block is half of described coil channel opening width.
The inboard of described block is provided with one to inclined-plane that the bottom land of coil groove tilts.
The cell wall that described coil channel opening place faces described inclined-plane is provided with for the positioning recess that slot wedge is installed.
The utility model is simple in structure, easy to process, cooperates adaptive slot wedge to be assembled into iron core, and the air-gap field of rotor is evenly distributed, reduce the harmonic wave that stator rabbet produces, reduce eddy current loss, reduce the intensification of motor, and then runnability and the useful life of improving motor.
Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments the utility model:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of coil groove of the present utility model.
Embodiment
As shown in Figure 1, a kind of ultrahigh speed permagnetic synchronous motor iron-core lamination structure comprises punching body 1100, and a plurality of punching bodies 1100 stack and can consist of iron core.
Evenly offer a plurality of coil grooves 1110 on the punching body 1100.
As shown in Figure 2, the opening part of coil groove 1110 is provided with a block 1111, and the length of block 1111 is half of coil groove 1110 A/Fs, forms the coil groove 1110 of half opening.
Particularly, the inboard of block 1111 is provided with one to the inclined-plane 1113 that the bottom land 1112 of coil groove 1110 tilts, and is convenient to fixedly slot wedge.
The cell wall that coil channel opening place faces inclined-plane 1113 is provided with for the fixing positioning recess 1114 of slot wedge.
Because coil groove 1110 is semi-open slot, therefore, embed in the coil groove 1110 after traditional coil windings need to being divided into multiply, slot wedge with high permeability seals opening again, so just reduced the harmonic wave that coil groove 1110 opening parts produce, reduce eddy current loss, thereby reduced the temperature rise of motor.
Ultrahigh speed permagnetic synchronous motor rotating speed generally can reach 6500r/min.
But, those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
