Abstract
The utility model discloses a high -efficient rotor of motor who enough reduce rotor resistance, reduces rotor loss, raises the efficiency, including to be folded by the rotor punching and pressing fashioned rotor core, the piece inslot injection of dashing of rotor punching has the die -casting aluminum strip, has still worn aluminium towards the piece inslot and has arranged or the copper bar. The elder generation is wearing aluminium and is arranging and then place in and cast the aluminum mould cast aluminium towards the piece inslot, can reduce the existence and the stray loss of gas pocket, shrinkage cavity and cold shut effectively, and copper bar and then cast aluminium are being worn towards the piece inslot, low -resistance characteristic of not only making the rotor have copper has guaranteed again that motor starting torque remains unchanged basically, reaches the purpose that improves the electric efficiency.
Description
Technical field
This utility model is related to motor technology field, and in particular to a kind of motor efficient rotor.
Background technology
Rotor of the prior art is mostly cast-aluminum rotor, wherein as pressure cast aluminium rotor labor intensity is low, production is imitated
Rate is high, and rotor presentation quality is good, most widely used, but pressure cast aluminium rotor aluminum strip internal flaw such as pore, shrinkage cavity, cold shut begin
Exist eventually, cause cast aluminium sliver resistance to increase, loss is increased；Between cast aluminium sliver and iron core, contact resistance is little simultaneously, transverse current
It is larger with stray loss.If substituting cast-aluminum rotor with copper casting rotor, the total losses of motor can be remarkably decreased, so as to carry
The whole efficiency of high motor, but the pouring temperature of copper die casting is at 1100 DEG C or so, and the pouring temperature of aluminum die casting is only 700
DEG C or so, so high pouring temperature is all very big test for the pressure chamber of mould and die casting machine；Copper casting rotor is electric simultaneously
Motivation has almost identical starting current with conventional motors, but as copper casting rotor is with lower than conventional aluminum rotor
Resistance, therefore, the detent torque of copper casting rotor motor is lower than conventional motors by 20% or so.
Utility model content
The utility model discloses one kind can reduce rotor resistance, reduce rotor loss, to carry efficient motor efficient
Rotor.
To achieve these goals, the technical solution adopted in the utility model is：A kind of motor efficient rotor, including by turn
Sub- punching laminates the rotor core of molding, and being full of in the punching groove of rotor punching has die casting aluminum strip, and aluminum row is also installed with punching groove
Or copper bar.
Aluminum row is first worn in punching groove and then cast aluminium in Cast Aluminum Dies is placed in again, pore, shrinkage cavity and cold can be efficiently reduced
Every presence and stray loss；And copper bar and then cast aluminium again are worn in punching groove, not only make rotor have low-resistance spy of copper
Property, in turn ensure that electric motor starting torque is held essentially constant, reach the purpose for improving electric efficiency.
Description of the drawings
Structural representations of the Fig. 1 for rotor.
Specific embodiment
As shown in figure 1, a kind of motor efficient rotor, including the rotor core that molding is laminated by rotor punching 10, rotor punching
Being full of in the punching groove 11 of piece has die casting aluminum strip 20, is also installed with aluminum row 30 or copper bar 40, referring specifically to following two in punching groove 11
Individual embodiment：
Embodiment 1
Determine the sectional area of die casting aluminum strip 20, aluminum row 30 first according to different rotors, rotor punching 10 is superimposed as rotor
Aluminum row 30 is worn after iron core, die casting in being subsequently placed in Cast Aluminum Dies, is carried out, aluminum row 30, die casting aluminum strip 20, end ring be combined together, and reduces
The defect such as pore during pressure cast aluminium inside aluminum strip is more, reduces the resistance of rotor；Simultaneously aluminum row 30 and rotor core connect
Resistance of getting an electric shock increases, and transverse current and stray loss reduce, and are effectively improved electric efficiency.
Embodiment 2
Die casting aluminum strip 20, the sectional area of copper bar 40 and relative position, rotor punching 10 are determined according to different rotors first
Copper bar 40 is worn after being superimposed as rotor core, copper bar 40 differently connects as needed, carried out in being subsequently placed in Cast Aluminum Dies
Die casting, copper, aluminum are combined together, and make low-resistance characteristic of the existing copper of rotor, reduce the loss of rotor, in turn ensure that motor is opened
Dynamic torque is held essentially constant, and reaches the purpose for improving electric efficiency.
In order that aluminum row 30 is reduced with the increase of rotor core contact resistance, transverse current and stray loss, aluminum row 30 is in
Autoxidation state or surface scribble high-temperature insulating paint or bag imines thin film, improve electric efficiency.
Claims (2)
1. a kind of motor efficient rotor, including the rotor core that molding is laminated by rotor punching (10), the punching groove of rotor punching
(11) being full of in has die casting aluminum strip (20), it is characterised in that：Aluminum row (30) or copper bar (40) are installed with punching groove (11) also.
2. motor efficient rotor according to claim 1, it is characterised in that：Aluminum arranges (30) in autoxidation state or table
Face scribbles high-temperature insulating paint or bag imines thin film.
