Abstract

The invention belongs to the technical field of assembly of cast aluminum rotors for high-voltage motors, and relates to a baffle structure, in particular to a baffle structure for a cast aluminum rotor of a high-voltage motor. The baffle structure for the cast aluminum rotor of the high-voltage motor adopts the technical scheme that a baffle comprises a baffle body; a mounting hole is formed in a central area of the baffle body; the hole diameter of the mounting hole is the same as the inside diameter of a rotor sheet body; and the baffle body on the outer side of the mounting hole can block off air holes in the rotor sheet body. The baffle structure is simple and compact in structure, low in cost, simple to process and manufacture, convenient to operate, and wide in application scope; omission or reverse placement is not easy; and the working reliability of the motor can be improved.

Description

technical field

[0001] The invention relates to a baffle structure, in particular to a baffle structure for a cast aluminum rotor of a high-voltage motor, and belongs to the technical field of assembling a cast aluminum rotor for a high-voltage motor. Background technique

[0002] For the high-pressure cast aluminum rotor motor with a box-type IP23 structure, the cold air in the motor's air path system enters the motor through the louvers at the non-shaft extension end of the motor, and enters the stator diameter through the air gaps in the axial ventilation holes of the rotor and the radial ventilation channels of the rotor shaft. To the ventilation channel, it flows through the end of the winding, and finally the internal fan discharges the hot air inside the motor from the louvers at the shaft extension end.

[0003] When the cold air flows through the cast aluminum rotor (the cast aluminum rotor is stacked by the rotor punch and the first rotor ventilation slot plate, an...
