Abstract
Disclosed is an internal wind path structure for a 2-pole motor, comprising an external wind path cooling flow channel and an internal wind path symmetric circular flow channel, wherein the external wind path cooling flow channel is fixedly provided with cooling pipes which are evenly distributed along the axial direction at the outboard of a rotor core, thus to form a cooling zone; the internal wind path symmetric circular flow channel is provided with penetrating radial ventilating ducts which are arranged at the side surfaces of the stator core and the rotor core; each end of the coil of the stator core is provided with a wind-guiding plate; and the outboard of the wind-guiding plate of each side is fixed in the cooling zone while the inside edge of each wind-guiding plate is provided with an axial-flow fan at a position close to the motor shaft. The utility model renews the arrangement of the internal wind path of a motor by improving the structure of the internal axial-flow fan. Two parallelly connected independent wind paths are changed into a mixed parallelly connected ventilation wind path. The static pressure and the dynamic pressure generated by an axial-flow fan are directly taken as the initial wind pressure of a rotor ventilating duct, thus to superpose the wind pressure generated by the rotor ventilating duct and the wind pressure generated by the axial-flow fan, thereby substantially improving the stator and rotor ventilating duct flow velocity, enhancing the cooling effect of the iron core, and improving the ventilation and heat radiation capability inside a motor.
Description
Technical field:
The utility model relates to the cooling technology of fire-proof motor, is specifically related to wind path structure in a kind of 2 utmost point motors.
Background technology:
In technique known, 2 dynamo-electric motivations are all selected the axial flow internal fan for use, and motor is independently two interior wind paths of symmetry.Article one, interior wind path is: the air quantity process end winding by the axial flow internal fan forms, end winding is cooled off the formation hot blast, and hot blast gets into cooler cooling back and forms cool breeze, and cool breeze process axial flow fan again circulates again; Another interior wind path is: the air quantity that is formed by the rotor radial air duct flows through surface, stator and rotor cores air channel, and the formation hot blast is cooled off on the rotor surface, and hot blast gets into cooler cooling back and forms cool breeze, and cool breeze is passed through the rotor radial air duct again from new circulation; The heat of motor mainly concentrates on the electric machine iron core position, and the rotor ventilation road is narrow and small, and the blast of formation is lower; And the windage at stator and rotor air duct place is bigger; Air quantity to stator and rotor cool off is less, sends a telegraph machine heat unshakable in one's determination and can not in time discharge, thereby cause that motor temperature is higher.
The utility model content:
The utility model utilizes the principle of the dynamic and static pressure stack of wind path to the deficiency of at present existing situation, proposes a kind of interior wind path arrangement.
The technical scheme that the utility model adopted: wind path structure in a kind of 2 utmost point motors comprises motor front end housing, rear end cap, stator core, rotor core; Support, motor reel is equipped with rotor core on the motor reel; External fan is loaded on the motor reel of rear end cap lateral wall; Comprise outer wind path coolant flow channel and interior wind path symmetrical cycle runner, said outer wind path coolant flow channel is to be uniformly distributed with vertically in the outside of stator core to be fixed with cooling water pipe, and the two ends of each cooling water pipe are fixed on the two end cap; The rear end of cooling water pipe is communicated with the air compartment of external fan, and cooling water pipe zone of living in forms the cooling zone; Wind path symmetrical cycle runner is to be respectively arranged with the radial ducts that runs through in the side of stator core and rotor core in said; And be provided with wind deflector at the coil two ends of stator core; The outer of every side wind deflector is fixed in the cooling zone; The edge is near being provided with axial flow fan in the wind deflector near the machine shaft, and the radial ducts of stator core and stator core coil chamber all are communicated with in the cooling zone.
Said axial flow fan is the water conservancy diversion fan blade that is fixed on machine shaft two end bearings.
Wind path is to mix parallelly connected ventilation road in said 2 utmost point motors, and static pressure that axial flow fan forms and dynamic pressure are directly as the initial blast in rotor ventilation road.
The useful good effect of the utility model:, make the interior wind path of motor arranged that again the independent wind path of two parallel connections becomes the parallelly connected ventilation wind path of mixing through improving the structure of internal fan axial flow fan.Static pressure that axial flow fan is formed and dynamic pressure are directly as the initial blast in rotor ventilation road; The blast that the rotor ventilation road is formed is superimposed with the blast of axial flow fan formation; Improve rotor air duct flow velocity greatly, strengthened cooling effect unshakable in one's determination, strengthened motor internal ventilation and heat ability.
