Description

Technical Field

[0001] The utility model relates to the technical field of air cooling for machining stator cores, in particular to an air cooling device for machining stator cores of generators. Background Art

[0002] At present, the stator core is an important component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and the rotor, it forms the complete magnetic circuit of the motor. In an asynchronous motor, the magnetic flux in the stator core is alternating, thus generating core loss. The core loss consists of two parts: hysteresis loss and eddy current loss.

[0003] Among them, the stator core is an important component of the stator and the main component of the motor magnetic circuit. It is composed of fan-shaped pieces, ventilation slots, positioning ribs, upper and lower tooth pressure plates, tensioning bolts and support plates.

[0004] During the processing, a large number of fan-shaped pieces need to be assembled together. In order to facilitate operation, the high-temperature fan-shaped pieces need to be air-cooled. However, most of the fan-shaped pieces on the market are air-cooled by fans, so the operator can only air-cool the fan-shaped pieces on one side, and the air-cooling efficiency is low. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
