Abstract
The utility model relates to a motor rotor structure, in particular to a motor aluminum casting rotor with a large fin. 8-12 trapezoid rotor-end annular fins (2) are uniformly distributed on the end surface of an excircle of two ends of a rotor core in sequence at intervals, and the lengths of the rotor-end annular fins (2) range from 40mm to 100mm. The motor aluminum casting rotor breaks through the design manner of small pins originally, the traditional pattern draft is changed to trapezoid design, the lengths of the rotor-end annular fins range from 40mm to 100mm, and the problem of electric clearance generated when a stator winding and the rotor rotate is solved. Large fins are additionally arranged on the annular end surface of the rotor core end, during the rotating process of the rotor, the surrounding air is stirred intensely, and windings at two ends of a motor are cooled, so that the temperature rising of the motor can be effectively reduced. In addition, a single balance ring is omitted, and an end ring balancing circular column for balancing is additionally arranged in a clearance between the rotor-end annular fins of a high-speed motor, so that the rotor balancing structure is simplified.
Description
Technical field
ThisUtility model relates to a kind of motor rotor construction, particularly relates to a kind of big fin apparatus for cast-aluminium rotor of electric machine structure.
Background technology
Traditional cast-aluminum motor rotor, the rotor end ring fin can not be excessive, is generally 20-70mm, otherwise can have influence on the mounting distance and the aluminum process property of the electric clearance and the rotor balancing ring of stator winding and rotor rotation; And traditional cast-aluminum motor rotor is designed with independent gimbal structure.The shortcoming that above-mentioned design exists is: less fin cooling capacity is relatively poor, independent gimbal structure more complicated.Therefore be necessary to propose further architecture advances, to improve the motor overall performance.
The utility model content
The utility model is not enough to prior art, proposes a kind of big fin apparatus for cast-aluminium rotor of electric machine structure, has broken through the design of in the past little fin, has solved the electric clearance problem between stator winding and the rotor;
In addition, between the rotor end ring fin, increased the end ring balance columns that is used for balance, simplified the rotor balancing structure for high-speed electric expreess locomotive.
The technical scheme that the utility model adopted:
A kind of big fin apparatus for cast-aluminium rotor of electric machine comprises rotor core (1), and the cylindrical end face is provided with the rotor end ring fin (2) of 8～12 trapezium structures successively uniformly at intervals at the two ends of said rotor core; The length of said rotor end ring fin (2) is between 40～100mm.
Described big fin apparatus for cast-aluminium rotor of electric machine, the center line and the rotor axis of the rotor end ring fin (2) of said trapezium structure are on the same straight line, and going to the bottom that rotor end ring fin (2) is bigger is connected with the two ends cylindrical end face one of rotor core.
Described big fin apparatus for cast-aluminium rotor of electric machine, rotor end ring fin (2) be shaped as isosceles trapezoid.
Described big fin apparatus for cast-aluminium rotor of electric machine is provided with 1～3 end ring balance columns (3) between per two adjacent rotors end ring fins (2).
The useful good effect of the utility model:
1, the big fin apparatus for cast-aluminium rotor of electric machine of the utility model has been broken through the design of in the past little fin, changes traditional pattern draft into trapezoidal design, rotor end ring finned length 40-100mm, the electric clearance problem when having solved stator winding and rotor rotation.Adopt the design of different smooth in the past end ring or little fin, increased big fin at rotor core end ring end face, in the rotor rotation process, strong agitation surrounding air is cooled off motor two ends winding, can reduce electric machine temperature rise effectively.
2, the big fin apparatus for cast-aluminium rotor of electric machine of the utility model has been cancelled independent gimbal, has increased the end ring balance cylinder (slowspeed machine does not have the balance cylinder) that is used for balance in the gap of rotor end ring fin for high-speed electric expreess locomotive, has simplified the rotor balancing structure.
