Abstract
The invention relates to a motor stator component structure with a magnetic slot wedge, which is characterized by comprising an upper stator coil and a lower stator coil which are arranged in a stator punching; the magnetic slot wedge is arranged below the lower stator coil, a top cushion is arranged between the top end surface of the upper stator coil and the bottom roof of the stator punching, a middle cushion is arranged between the top end surface of the lower stator coil and the bottom end surface of the upper stator coil, an adjustment cushion and an expansion cushion are arranged between the bottom end surface of the lower stator coil and the bottom frame of the stator punching, the adjustment cushion is arranged below the expansion cushion, and the top end surface of he magnetic slot wedge is in contact with the bottom end surface of the adjustment cushion. The magnetic slot wedge of the invention can effectively improve the magnetic potential wave shapes of air gaps, reduce exciting currents, increase the power factors and efficiency of a motor, and reduce the temperature rise, noise and vibration of the motor. The magnetic slot wedge can ensure that the motor can be reliably fixed in the stator slot shape during the operation process without phenomena of loosing, cracking, tissue loosing, surface bubbling and the like, thus avoiding the friction between the stator and the rotator of the motor caused by the cracking, loosing, dropping and the like of the magnetic slot wedge.
Description
Technical field
The present invention relates to a kind of motor stator modular construction, especially a kind of motor stator modular construction with magnetic slot-seal device.
Background technology
At present, international energy is becoming tight more, and energy savings is more and more important.If the use magnetic slot-seal then concerning stator is the open slot high-voltage motor, can obviously reduce the wastage, raise the efficiency, and can reduce electric machine temperature rise (electric machine temperature rise of magnetic slot-seal hangs down 18% approximately than non magnetic slot wedge), reduction noise.After yet early stage domestic electric machine factory used magnetic slot-seal, motor operation a period of time, phenomenons such as that magnetic slot-seal is organized is loose, surface blisters even cracking were so until nowadays, all stopped the use magnetic slot-seal.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, thereby provide a kind of magnetic slot-seal no longer to produce cracking, organize phenomenons such as loose, surface blisters to save motor cost, improved the motor stator modular construction with magnetic slot-seal of electric efficiency.
According to technical scheme provided by the invention, described motor stator modular construction with magnetic slot-seal, be included in the last stator coil and following stator coil that are provided with in the stator punching, following stator coil below is provided with magnetic slot-seal, be provided with the top pad at the bottom of last stator coil top end face and the stator punching between the top, be provided with middle pad between stator coil top end face and the last stator coil bottom face down, be provided with adjusting pad and expansion block between stator coil bottom face and the stator punching underframe down, adjusting pad is arranged on the expansion block below, and described magnetic slot-seal top end face contacts with the adjusting pad bottom face.The both sides of while magnetic slot-seal and the notch and the higher glue of the uniform brushing class of insulation of top ends of stator slot shape.
Advantage of the present invention: the new magnetic slot-seal of this practicality can effectively improve the magnetic potential of air gap waveform, reduces exciting curent, improves motor power factor, efficient, reduces electric machine temperature rise, noise, vibration; Can guarantee in the motor operation course, be fixed on reliably in the stator slot shape, phenomenons such as loose, surface blisters no longer occur becoming flexible, ftracture, organizing, thereby avoided the cracking because of magnetic slot-seal, the electric machine rotor of generation such as become flexible, come off to wipe mutually.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is the left view of magnetic slot-seal among the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: the present invention mainly by stator punching 1, go up stator coil 2, stator coil 3, magnetic slot-seal 4, top pad 5, middle pad 6, adjusting pad 7 and expansion block 8 etc. constitute down.
This has the motor of magnetic slot-seal device, be included in the last stator coil 2 and following stator coil 3 that are provided with in the stator punching 1, following stator coil 3 belows are provided with magnetic slot-seal 4, be provided with top pad 5 between last stator coil 2 top end faces and the top, 1 end of stator punching, pad 6 in being provided with between stator coil 3 top end faces and last stator coil 2 bottom faces down, be provided with adjusting pad 7 and expansion block 8 down between stator coil 3 bottom faces and stator punching 1 underframe, adjusting pad 7 is arranged on expansion block 8 tops, and described magnetic slot-seal 4 top end faces contact with expansion block 8 bottom faces.
Expansion block 8 has adopted a kind of new material-thermal expansivity glass felt, coefficient of thermal expansion is with 〉=50% behind 80 ℃ of this materials, the 30min, make motor stator behind preliminary drying, dipping lacquer, expansion block 8 effectively expands, make in the motor operation course, the vibration that magnetic slot-seal no longer produces because of the gap, thus useful life of magnetic slot-seal prolonged.
The higher glue of the uniform brushing class of insulation of the both sides of magnetic slot-seal and the notch of stator slot shape and top ends.Avoid the slot wedge loosening of magnetic slot-seal because of produced by magnetic pull and localized hyperthermia in the motor operation course, thereby guaranteed the reliable use of magnetic slot-seal.
Claims (2)
1. motor stator modular construction with magnetic slot-seal, be included in the last stator coil (2) and following stator coil (3) that are provided with in the stator punching (1), following stator coil (3) below is provided with magnetic slot-seal (4), it is characterized in that: go up and be provided with top pad (5) between stator coil (2) top end face and stator punching (1) end top, be provided with middle pad (6) between stator coil (3) top end face and last stator coil (2) bottom face down, be provided with adjusting pad (7) and expansion block (8) down between stator coil (3) bottom face and stator punching (1) underframe, adjusting pad (7) is arranged on expansion block (8) top.
