Description
Technical field
The utility model relates to a kind of compressor electric motor parts, and more particularly, it relates to a kind of small-rabbet stator punching sheet of motor that can improve magnetic flux.
Background technology
Along with country advocates energy-saving and emission-reduction energetically, each Compressors Factory to improve the compressor electric motor performance, reaches energy-conservation purpose by continuous technological improvement.In the manufacture process of refrigeration compressor motor, need to use motor stator punching, several wiring slots are set on stator punching, coil is installed in wiring slot.In actual production process, the width of rebate of wiring slot generally designs widelyr, the loss of the larger motor of width of rebate is just larger, electric efficiency reduces, the temperature rise of motor is higher, therefore the width of the wiring slot of stator punching is the smaller the better, the little loss that just can reduce motor of the width of rebate of wiring slot, the efficiency of raising motor, reduce the temperature rise of motor.But the width of wiring slot notch is too little, just coil can't be installed in wiring slot, therefore the width of wiring slot notch generally designs between 1.6-2.3mm at present, and minimum also can only accomplish 1.4mm.
Chinese patent notification number CN202309257U, a kind of motor stator punching is disclosed, comprise the punching body, punching body center is provided with a manhole, and the inwall of manhole is provided with some punching grooves that are evenly distributed, and the punching groove comprises favourable opposition film trap and little punching groove, the width of rebate of favourable opposition film trap is 2.1-2.3mm, groove shoulder breadth degree near notch is 4.5-4.7mm, and the groove height is 12-12.2mm, and the radius of the semi arch of trench bottom is 3.8mm-4mm; The slot opening of little punching groove is 2.1-2.3mm, and the groove shoulder breadth degree of close notch is 4.5-4.7mm, and the groove height is 9.7-9.9mm, and the radius of the semi arch of trench bottom is 3.5-3.7mm.The punching groove width of rebate of the stator punching of this structure is larger, facilitate coil to be installed in the punching groove, but punching groove width of rebate is large, and the loss of motor is just larger, and electric efficiency reduces, and the temperature rise of motor is higher.
The utility model content
The utility model has overcome the deficiency of existing stator punching two aspects: the one, and, the width of rebate of wiring slot that coil installs rear stator punching is larger, has increased the loss of motor, has reduced the efficiency of motor, has increased the temperature rise of motor; The 2nd,, the stator punching that the wiring slot width of rebate is less is installed the coil difficulty, and coil assembly work efficiency is low.The utility model provides a kind of small-rabbet stator punching sheet of motor, and the width of rebate that coil installs rear stator punching wiring slot is less, has reduced the loss of motor, has improved the efficiency of motor, has reduced the temperature rise of motor.And coil is installed in the wiring slot of less width notch conveniently, coil assembly work efficiency is high.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of small-rabbet stator punching sheet of motor, comprise the punching body, the punching body is provided with through hole, on the sidewall of through hole along several wiring slots that is provided with in a week of through hole, on the punching body, the position, two edges of wiring slot notch is equipped with prolonged bar, be arranged on that two prolonged bars in same notch are oppositely arranged and they between be provided with gap, prolonged bar vertically bends setting.
Several stator punchings are superimposed, wiring slot on the punching body is corresponding the coincidence one by one, coil inserts in wiring slot and is arranged in wiring slot in the gap between adjacent two prolonged bars, flatten the prolonged bar that vertical bending arranges after the coil installation, distance between adjacent two prolonged bars reduces greatly, and the width of rebate that is equivalent to wiring slot reduces, and has reduced the loss of motor, improve the efficiency of motor, reduced the temperature rise of motor.And, when coil is installed, because prolonged bar is that vertical bending arranges, the gap between adjacent two prolonged bars is larger, facilitates coil to be installed in wiring slot.In sum, the width of rebate that coil installs rear stator punching wiring slot is less, has reduced the loss of motor, has improved the efficiency of motor, has reduced the temperature rise of motor.And coil is installed in the wiring slot of less width notch conveniently, coil assembly work efficiency is high.
As preferably, all prolonged bars all upwards bending arrange, the bending angle of prolonged bar is 30 degree-60 degree.Prolonged bar all upwards bending arrange, the be superimposed applanation process of rear prolonged bar of all stator punchings is more convenient.And the bending angle of prolonged bar arranges rationally, can not make because angle is too little the installation difficulty of the too small increase coil of distance between adjacent two prolonged bars, can not make prolonged bar the phenomenon fractureed occur because angle is too large yet.The another kind scheme, upwards bending setting of adjacent two prolonged bar, a downward bending setting, and all prolonged bars upwards bend and bending downwards is arranged alternately successively, and the bending angle of prolonged bar is that 30 degree-60 are spent.One of adjacent two prolonged bar is downward bending of bending upwards, after all stator punchings are superimposed, the top and the width of rebate of the wiring slot of the stator punching of below be greater than one of adjacent two prolonged bar upwards bending the width of rebate that a downward bending arranges the wiring slot of formation is set, make coil be installed to the process of wiring slot more convenient.
As preferably, the prolonged bar width is from reducing gradually with the end of punching body link position to prolonged bar.The position of prolonged bar bending is at the link position of prolonged bar and punching body, and prolonged bar is larger at the width with punching body link position, just can increase the bonding strength of prolonged bar, makes not to be prone to the phenomenon fractureed in the process of prolonged bar bending and pressing.
As preferably, wiring slot is along uniform setting in a week of through hole, and the width of wiring slot increases to bottom land gradually from notch, and the bottom land of wiring slot is the arcuate structure of indent.The width of wiring slot thinks that from notch bottom land increases gradually, makes coil more convenient in the process of the wiring slot of packing into.
As preferably, the width of rebate of all wiring slots is consistent, and the length of all prolonged bars is consistent.Width of rebate is consistent, and prolonged bar length is consistent, and versatility is good, and coil can be inserted in any one wiring slot, flexible.
Compared with prior art, the beneficial effects of the utility model are: it is less that small-rabbet stator punching sheet of motor makes coil install the width of rebate of rear stator punching wiring slot, reduced the loss of motor, improved the efficiency of motor, reduced the temperature rise of motor.And coil is installed in the wiring slot of less width notch conveniently, coil assembly work efficiency is high.
