The technical solution of the utility model includes: the cast-aluminum rotor of rubber machine motor, including rotor core, rotor core both ends
Equipped with cooling wind blade；The middle part of the rotor core is B rotor punching area, and the two sides in B rotor punching area are respectively the first A rotor
Punching area and the 2nd A rotor punching area；B rotor punching area is formed by 6~10 B rotor punching closed assemblies；First A
Rotor punching area and the 2nd A rotor punching area are formed by one group of A rotor punching closed assembly；The middle part of the A rotor punching is equipped with
The middle part of oblique key slot axis hole, the B rotor punching is equipped with flat key fluted shaft hole；It is circumferentially uniformly provided on the A rotor punching
One group of open slot, it is corresponding, the identical closed slot of one group of quantity is circumferentially uniformly provided on the B rotor punching；It is described to close
The area of mouth slot is greater than open slot；A rotor punching in the first A rotor punching area and the 2nd A rotor punching area is in mutual
Reversed skew shape, to form chevron-notch in the side of rotor core.
Compared with prior art, the utility model, which efficiently solves, be easy to cause rotor sky aluminium, breaks in existing aluminum process
The case where；The cast-aluminum rotor of the utility model is made of the two kinds of different punchings of structure of A rotor punching and B rotor punching, A
The structure of rotor punching can effectively improve the working efficiency and detent torque of cast-aluminum rotor, while B rotor punching is equipped with spy
Determine the closed slot of groove profile, the area of closed slot is greater than open slot, passes through conducive to aluminium when carrying out aluminium die casting, turns to prevent
The case where sub- sky aluminium, broken strip；Rotor core is equipped with chevron-notch (herringbone skewed slot), and rotor is made to generate two after powered up
Contrary and symmetrical axial force, resultant force zero thus greatly reduce loss, have saved the energy, improve motor
Working efficiency and service life.
As optimization, the gradient of the chevron-notch is 5 °.Chevron-notch has specific skew slot angle, not only can effectively slacken
Interaction between rotor slot ripples and stator harmony wave reduces synchronous additional torque, vibration and noise, and mitigates
Influence of the flume structure to motor torque capacity and power factor.
As optimization, the B rotor punching with a thickness of 0.5mm, the quantity of B rotor punching is 6.Pass through specific thicknesses
And the structural strength of cast-aluminum rotor middle section can be effectively ensured in the B rotor punching of quantity, prevent cast aluminium conducting bar from broken strip occurs.
