Abstract
The invention relates to a motor rotor punching sheet with asynchronous starting and synchronization running, belongs to a rotor core punching sheet of a synchronous motor, and can be compatible with a speed motor, a water pump motor, a blower fan motor, a compressor motor, an injection machine motor, a blowing machine motor, a rubber and plastic machinery motor and the like. The motor rotor punching sheet comprises a punching sheet body which is uniformly provided with a starting bar groove at periphery, the rotor punching sheet body under the starting bar groove is uniformly distributed with 33 magnetic steel grooves. A middle part of the rotor punching sheet body is provided with a rotor shaft hole, and a diameter of the rotor punching sheet body is 147-150 mm.
Description
Technical field
What the present invention relates to is the synchronous operated synchronous electric motor rotor punching of a kind of asynchronous starting, belongs to the rotor core punching field of motor
Background technology
Present motor rotor punching sheet, because the rotor punching structural design is reasonable inadequately, the running of can not pulling in smoothly behind the electric motor starting.Because the rotor punching structural design is reasonable inadequately, brings the unreasonable locked-rotor torque that causes of magnetic intensity bigger than normal, simultaneously, unreasonable the causing of back electromotive force is not economized on electricity.Electric machine rotor punching burr is excessive to motor complete machine quality, and electric property has serious harm.Because crossing ambassador's stacking factor unshakable in one's determination, reduces burr, equally influential inadequately with stator and rotor cores weight to electric property.Burr is crossed ambassador's stator core tooth portion degree of flicking greater than permissible value, can cause that power factor reduces, and copper loss increases, and temperature rise is increased.Press-fit short circuit between the stator iron-core lamination of back, eddy current loss increases.
Summary of the invention
Technical problem to be solved by this invention is to provide rotor punching a kind of simple in structure, reasonable in design.Technical problem to be solved by this invention adopts following technical scheme to realize,
A kind of motor rotor punching sheet; Comprise the rotor punching body, the external starting bar groove that is evenly distributed in of rotor punching is evenly equipped with 33 magnet steel grooves on rotor punching body below the starting bar groove; Being provided with rotor shaft hatch at rotor punching body middle part, is 147-150mm in the described rotor punching body diameter.
Described starting bar groove is set to 90-120.It is trapezoidal that described magnet steel slot part is opening, and the magnet steel groove depends on the axial long 2.6mm of rotor, and open upper end is long to be 1mm; The rail height is 20.5mm; The flute profile dimensional tolerance is pressed the H10 of GB1801-79, and the width dimensions tolerance of notch is pressed the H12 of GB1801-79, and the rail height is more or less the same in 0.2mm.
The invention has the beneficial effects as follows: the present invention compared with prior art, it is simple and reasonable, saves power supply more.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of magnet steel groove of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
Like Fig. 1, shown in Figure 2; A kind of motor rotor punching sheet; Comprise rotor punching body 1, rotor punching body 1 excircle is evenly equipped with starting bar groove 4, on rotor punching body 1 below the starting bar groove 4, is evenly equipped with 33 magnet steel grooves 2; Being provided with rotor shaft hatch 3 at rotor punching body 1 middle part, is 147-150mm in described rotor punching body 1 diameter.
Described starting bar groove 4 is set to 90-120.It is trapezoidal that described magnet steel groove 2 parts are opening, and magnet steel groove 2 depends on the long 2.6mm of rotor shaft hatch direction, and open upper end is long to be 1mm; The rail height is 20.5mm; The flute profile dimensional tolerance is pressed the H10 of GB1801-79, and the width dimensions tolerance of notch is pressed the H12 of GB1801-79, and the rail height is more or less the same in 0.2mm.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
