Description
Technical field
The utility model relates to a kind of baffle arrangement, and especially a kind of high-voltage motor cast-aluminum rotor baffle arrangement belongs to the technical field of cast-aluminum rotor assembling for high-voltage motor.
Background technology
High-voltage cast-aluminum rotor electric machine for box IP23 structure, in the air path system of motor, cold air enters motor internal by the shutter of motor non-shaft stretching end, air gap by rotor axial ventilation hole, armature spindle radial ducts enters stator radial ducts, the winding overhang of flowing through, is finally discharged the hot-air of motor internal by internal fan by shaft extension end shutter.
When cold air is flowed through cast-aluminum rotor (after cast-aluminum rotor laminates by rotor punching and the first rotor ventilation channel plate, then in cast-aluminum rotor one end, put a slice the second rotor ventilation frid, through the final cast-aluminum rotor that forms of aluminium ingot cast), thereby the air gap by rotor axial ventilation hole and armature spindle radial ducts enters the object that stator radial ducts reaches cooling stator core and cast-aluminum rotor, so generally all will put in one end of cast-aluminum rotor a slice the second rotor ventilation frid part, block rotor axial ventilation hole, reach and allow cold air flow along rotor radial ducts, if need not block rotor axial ventilation hole by the second rotor ventilation frid, cooling air can flow to fan by the direction of straight line along rotor axial ventilation hole and finally discharge motor, like this, cooling effect is very poor, fixed, rotor core temperature can be very high.But in the process of cast, the workman in workshop is easy to the second rotor ventilation frid part to forget, once forgetting, pour into a mould molded being difficult to again of cooling rear cast-aluminum rotor reforms, or press-fit in process and easily will have one end of the second rotor ventilation frid to put back at cast-aluminum rotor, final result is directly to cause the wind path that rotor axial ventilates entirely to be blocked, and is easy to burn-down of electric motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of high-voltage motor cast-aluminum rotor baffle arrangement is provided, and it is simple and compact for structure, cost is low, and processing and fabricating is simple, easy to operate, be not easy to omit or put back, wide accommodation, can improve the reliability of machine operation.
The technical scheme providing according to the utility model, described high-voltage motor cast aluminium rotor baffle arrangement, described baffle plate comprises baffle plate body, the center of described baffle plate body arranges installing hole, the aperture of described installing hole is identical with the internal diameter of rotor punching body, the air vent hole on the baffle plate physical efficiency shutoff rotor punching body of installing hole outer ring.
The aperture of described installing hole is 195mm, and the external diameter of baffle plate body is 280mm.Described baffle plate is circular.
Described baffle plate is enclosed within on armature spindle by installing hole, and is positioned at one end of rotor; One end of armature spindle arranges air feed shutter window, and the other end of armature spindle arranges air-out shutter, and the top of air-out shutter arranges internal fan.
Advantage of the present utility model: can by baffle plate in advance hot jacket on armature spindle, then on armature spindle, press-fit cast-aluminum rotor, can in cast-aluminum rotor assembling process, leak the phenomenon of putting the second rotor ventilation frid or the second rotor ventilation frid being put back, the air vent hole of baffle plate energy shutoff rotor punching body, can meet the air-conditioning requirement of cold air to cast-aluminum rotor, simple and compact for structure, cost is low, processing and fabricating is simple, easy to operate, be not easy to omit or put back, wide accommodation, can improve the reliability of machine operation.
