Description

Technical Field

[0001] The utility model relates to the field of paint-free motors, and particularly relates to a stator winding structure of a paint-free motor. Background Art

[0002] Unpainted motors refer to motors whose iron cores and coils are not painted during the production process. Painted motors, on the other hand, are motors whose iron cores and coils are dipped in paint to form a protective layer. The low-power, low-voltage 120-240V motors currently manufactured on the market are composed of a stator assembly and a rotor assembly. Currently, the stator assembly is coated with insulating paint to prevent the insulating slot wedges and slot paper from falling off and the coil winding from loosening. However, the current paint process on the market requires paint dipping in a designated paint tank, which is cumbersome to operate and inconvenient for subsequent maintenance.

[0003] Therefore, in order to solve the deficiencies in the prior art, a simple structure of a paint-free motor stator winding structure needs to be designed. Utility Model Content

[0004] The utility model provides a stator winding structure of a paint-free motor to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a paint-free motor stator winding structure comprises: a stator, a winding, a guide plug, a lower guide plate one, a lower guide plate two and a partition, the winding ring is arranged in the inner cavity of the stator, the inner side of the inner cavity is ringed with a heat dissipation port, the guide plug comprises an upper guide plate and a vertical plug, the vertical plug is arranged in a ring at intervals and distributed on the inner side of the guide plate, the vertical plug is arranged opposite to the heat dissipation port, the upper guide plate, the lower guide plate one and the lower guide plate two are all provided with a plurality of groups of guide holes, the guide holes of the upper guide plate are arranged opposite to the winding gap, the upper guide plate is located at the upper end of the winding, the lower guide plate one and the lower guide plate two are sequentially arranged downward at the lower end of the winding, an annular block is arranged in the middle of the upper guide plate, the annular block and the inner cavity form a liquid adding cavity, the partition is arranged at the lower end of the lower guide plate two, and the partition, the lower guide plate two and the inner cavity form a storage cavity.

[0006] As a further improvement, the cross-sectional width of the guide holes of the upper guide plate is increased downward.

[0007] As a further improvement, an inner ring of the lower guide plate is provided with a socket for the vertical plug-in plate to be plugged in.

[0008] As a further improvement, an outer cover is provided at the top of the stator, and screws threadedly connected to the annular block are provided on the outer cover.

[0009] Compared with the prior art, the stator winding structure of the paint-free motor of the utility model has the following beneficial effects:

[0010] The vertical plug plate is directly opposite to the heat dissipation port and closes the heat dissipation port to ensure that the paint dipping liquid does not flow out inward. At the same time, the guide holes in the lower guide plate 1 and the lower guide plate 2 are alternately arranged to prevent the paint dipping liquid from seeping down. The paint dipping liquid is added into the liquid adding chamber, and the paint dipping liquid slowly flows downward into each gap of the winding through the small guide holes on the upper guide plate to infiltrate the winding. After infiltration for a specified time, the guide plug plate is rotated to drive the lower guide plate 1 below, so that the guide holes of the lower guide plate 1 and the lower guide plate 2 are connected. At the same time, the heat dissipation port is opened to ensure the heat dissipation of the subsequent stator operation, so that the excess liquid enters the storage chamber, and finally the excess liquid is solidified in the storage chamber without secondary treatment. The operation is simple and efficient, and part of the stator can replace the traditional dipping process without the need for dipping equipment. BRIEF DESCRIPTION OF THE DRAWINGS
