Abstract
The utility model discloses an air path on the inlet side of an inner fan in a cage-shaped motor, and relates to a cage-shaped motor. The air path comprises a rotor iron core and an inner fan, as well as a rotor axial air duct fixed between the inner fan and the rotor iron core, wherein the rotor axial air duct comprises an air duct base, an air duct support and an air duct, and the air duct is fixed on the air duct base via the air duct support. According to the air path provided by the utility model, the axial lengths of the external cover and the blades of the inner fan are shortened, and the problem of poor reliability of the inner fan is solved; the casting cost is lowered, and casting defects are reduced; and the rotor axial air duct is added to reduce wind resistance and eddy current loss, effective air flow capacity is increased, and the working efficiency is improved.
Description
Technical field
The utility model relates to the cage modle motor, is specifically related to a kind of cage modle motor internal fan entrance side wind path.
Background technology
In the cage modle motor, inner ventilation is to produce blast by the fan in the motor, and inner air flow through winding overhang, rotor air channel, stator air channel bring to heat in the radiating ribs of support at last.Inner wind path design rationally whether, with temperature rise that directly influences complete machine and useful life.And internal fan is unique power original paper of inner wind path, so the structure of its entrance and exit side becomes the wind path key for design.
The internal fan entrance side wind path structure of existing cage modle motor comprises rotor core 1 and internal fan 2, and the enclosing cover 4 of internal fan 2 extends near the end ring 3 of rotor core, the flabellum 5 corresponding lengthenings of internal fan 2, and its basic structure is as shown in Figure 1.There is following defective in the crosswind road of this structure: the enclosing cover and the flabellum axial length of (1) internal fan are longer, the corresponding reduction of its intensity and rigidity, and the internal fan reliability is low; (2) internal fan adopts casting aluminium material, and the long casting cost that causes of its axial length increases, and casting flaw increases, and can reduce the internal fan reliability equally.
Summary of the invention
The purpose of the utility model is for a kind of cage modle motor internal fan entrance side wind path is provided.
The utility model is realized through following technical scheme:
A kind of cage modle motor internal fan entrance side wind path; Comprise rotor core and internal fan; Also comprise the rotor axial ventilating duct that is fixed between internal fan and the rotor core; Described rotor axial ventilating duct comprises wind-guiding cylinder base, ventilating duct support and ventilating duct, and ventilating duct is fixed on the wind-guiding cylinder base through the ventilating duct support.
The utility model has shortened the enclosing cover of internal fan and the axial length of flabellum, has improved its intensity and stiffness, has solved the problem of fan poor reliability; Reduce the casting cost, reduced casting flaw simultaneously; Between fan and rotor core, increase the rotor axial ventilating duct in addition, reduced windage and eddy current loss, increased effective air mass flow, guaranteed the axial passage of wind path, made it get into fan reposefully, improved operating efficiency.
