For above-mentioned motor, if go up alternately making current at coil (13), the electric current that flows through above-mentioned coil (13) so can produce interaction force, under the effect of this active force, rotor (2) rotation, meanwhile, rotating shaft (3) can link with rotor (2), thus rotation.
The manufacturing process of the rotor of aforesaid existing cage shape (2) promptly at first stacks up many silicon steel plates according to following order, thereby produces the rotor core (21) of a plurality of through holes (21b); Then the rotor core made from said method (21) is placed in the mould (aluminum die casting tool) that the aluminium die casting uses, and carry out the aluminium die casting, the aluminium of fusion is filled into respectively in the through hole (21b) of rotor core (21), thereby form stub (22), meanwhile, also form the annular short-circuited conducting sleeve (23) that links into an integrated entity with stub (22) at the two ends of rotor core (21).
But, the rotor (2) of the cage shape of above-mentioned existing motor, though a variety of materials higher than the conductivity of aluminium are arranged, but why still adopt the method for aluminium die casting (aluminum diecasting) to make stub (22) and short-circuited conducting sleeve (23), be because the fusing point of aluminium is lower, carry out die casting (die casting) easily.But this can bring following problem, promptly owing to be subjected to the restriction of the conductivity of aluminium, therefore has certain limitation aspect the efficient that improves motor.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing motor exists, the invention provides a kind of rotor and manufacture method thereof of cage shape of motor, it can reduce impedance by the method for making stub and short-circuited conducting sleeve with the higher material of conductivity, thereby improves the efficient of motor.
The rotor of the cage shape of motor of the present invention adopts following technical scheme:
A kind of rotor of cage shape of motor is characterized in that, comprises rotor core, makes with soft magnetic material, is cylindric; A plurality of stubs are the outer rings that are inserted in described rotor core along the vertical direction, are made of copper; Short-circuited conducting sleeve in order realizing being electrically connected with described each stub, to be installed in the top and bottom of rotor core respectively, and to be made of copper.
The rotor of the cage shape of described motor, wherein each stub is that inclination certain angle ground is installed.
The method for manufacturing rotor of the cage shape of motor of the present invention adopts following technical scheme:
A kind of method for manufacturing rotor of cage shape of motor, it is characterized in that, its fabrication schedule carries out according to following order, promptly make the stage of short-circuited conducting sleeve assembly, copper stub is installed between top short-circuited conducting sleeve that is being made of copper in this stage and the bottom short-circuited conducting sleeve, thereby form the short-circuited conducting sleeve assembly, these stubs keep being electrically connected with upper and lower short-circuited conducting sleeve at a distance of certain intervals; Form the stage of columnar rotor core, in this stage, described short-circuited conducting sleeve assembly is placed in the mould, and carry out extrusion forming processing, be positioned at the rotor core that its inside, short-circuited conducting sleeve are positioned at its upper/lower terminal thereby form stub with soft magnetic material.
