Description
Technical field
The utility model relates to the electromagnetic structure field of large, medium and small high-low pressure asynchronous motor, particularly a kind of Novel motor rotor punching.
Background technology
Modern society to the energy-saving and emission-reduction of the equipment of industrial product and environmental requirement more and more higher, than common electric machine, there is more high efficiency high efficiency motor to receive much concern in market, high efficiency motor adopts electromagnet design, the loss of electromagnetic energy, heat energy and mechanical energy is reduced by the optimal design etc. of new technology and new diseases, ventilating and cooling, significantly improve delivery efficiency, therefore the efficiency of high efficiency motor on average can improve 4% than common electric machine.Because the copper loss of asynchronous motor rotor occupies larger proportion in motor total losses, the design therefore with low rotor copper loss is extremely important for high efficiency motor, but copper loss of rotor consumption will be reduced just must reduce rotor cage resistance, but this can affect the starting performance index that motor comprises starting current and starting torque.For utilizing kelvin effect during electric motor starting, existing motor rotor punching sheet is by getting around the effect of establishing the slotted eye of same shape to play and controlling starting current and increasing starting torque in the punching pressed on ring of annular, this single slotted eye design can produce the too sparse and serious uneven phenomenon that bottom is saturated in magnetic close distribution rotor tooth top, affects stock utilization and power of motor greatly.
Utility model content
The major technique task of the main technical problems to be solved in the utility model and proposition is to provide a kind of Novel motor rotor punching, described punching reduces rotor copper loss by the slotted eye design changed on it, improve electric efficiency and starting torque simultaneously, reduce starting current, high to stock utilization, reduce motor volume more further and provide possibility.
The utility model adopts following technical scheme: a kind of Novel motor rotor punching, comprise the punching body of an annular, described punching body has uniform slotted eye around circumference, it is characterized in that described slotted eye comprises staggered first slotted eye and the second slotted eye, large outer little in first slotted eye, outer peripheral edges one end of punching body is less than inner peripheral one end, and the outer imperial palace of the second slotted eye is little, and outer peripheral edges one end of punching body is greater than inner peripheral one end.Uniform and be staggered around circumference at punching body by the slotted eye of shape single on existing rotor punching being made into two kinds of specification slotted eyes, first narrow the inner, slotted eye outer end is wide, second money the inner, slotted eye outer end is narrow, the rotor cage existing operation resistance of this design forming is little has again the good advantage of kelvin effect, make the channel-shaped portion close distribution of rotor tooth yoke portion magnetic exceptionally more reasonable, electric efficiency can be improved while minimizing rotor copper loss, and improve starting torque reduction starting current, high to stock utilization, motor volume is reduced becomes possibility.
As improving further and supplementing technique scheme, the utility model adopts following technical measures: the first described slotted eye and the second slotted eye are mutual inverted water-drop-shaped hole, the outer end of the first slotted eye is the tip of water droplet, and the inner of the second slotted eye is the tip of water droplet.The wide end in water-drop-shaped hole and narrow end ratio are obvious, have preferably kelvin effect performance, for improving electric efficiency and starting torque, reduction starting current, improve stock utilization and have effect clearly.
The first described slotted eye and the second slotted eye are mutual inverted trapezoidal hole or pyriform hole.Except water-drop-shaped hole, also can be the narrow shape in trapezoidal hole or pyriform hole wide one end, this obvious one end, for improving electric efficiency and starting torque, reduction starting current, improve stock utilization and have effect clearly.
The first described slot aperture forms breach in the outer peripheral edges of punching body after extending.Breach contributes to the exhaust of deep bar rotor in cast aluminium process, improves cast aluminium quality; Meanwhile, the slotted eye of opening is conducive to reducing groove leakage reactance, improves motor runnability.
The utility model changes existing punching body only has the slotted eye of single shape design, punching body is offered two kinds of circumferences uniform and staggered first slotted eye and the second slotted eye, first narrow the inner, slotted eye outer end is wide, second money the inner, slotted eye outer end is narrow, the rotor cage existing operation resistance of this design forming is little has again the good advantage of kelvin effect, make the channel-shaped portion close distribution of rotor tooth yoke portion magnetic exceptionally more reasonable, electric efficiency can be improved while minimizing rotor copper loss, and improve starting torque reduction starting current, high to stock utilization, motor volume is reduced and becomes possibility.
