Background
The stator coil of the electronic expansion valve is a power driving source applied to an external unit of the variable frequency air conditioner to control the valve body of the electronic expansion valve. When the stator coil is used, the quality of fusion of the edge part of the framework and the encapsulating material directly influences the quality of the water resistance of the stator coil, so the control requirement on the process is strict when the stator coil is encapsulated. When the coil is in plastic package, the edge of the framework is thick, and the heat of the packaging material is not enough to promote the edge to be melted, so that the coil framework and the packaging resin are not completely fused together after molding. When the coil is in a water immersion state, water can permeate into the coil from a place with poor bonding between the framework and the encapsulation resin, so that water enters the coil, the coil is poor in insulation, failure is caused, and a series of dangers such as electrification of an external unit are caused.
