Description

Technical Field

[0001] The utility model relates to the technical field of winding drying, in particular to a motor winding dryer. Background Art

[0002] Windings are a general term for multiple coils or coil groups that form a single phase or the entire electromagnetic circuit. Motor windings utilize a large amount of insulating materials, such as cardboard, cable paper, and telephone paper. Under normal conditions, these materials contain 6-8% moisture by mass, which absorbs moisture from the air during the winding manufacturing process. This moisture can affect the electrical strength of the insulation material. Furthermore, when the insulating fiber material becomes damp, its thickness expands, affecting the axial dimensions of the windings. This can lead to errors in subsequent assembly, hindering subsequent work progress, and compromising the insulation material's performance, increasing production costs. Utility Model Content
