Abstract

A sealant stator, which includes a stator group, a circuit board and sealant. The stator set includes an iron core and a coil, the coil is wound and combined with the iron core; the circuit board is electrically connected to the coil, and the circuit board is provided with glue injection holes and ventilation holes; the sealant covers the stator set and the circuit board; wherein the glue injection hole of the circuit board is used to shorten the flow path of the sealant when it is injected into a mold.

Description

technical field [0001] The invention relates to a sealed stator, in particular to a structure in which the stator can be integrally covered with glue. Background technique [0002] Please refer to figure 1 As shown, the existing rubber-sealed stator 9 has a magnetic pole piece group 91, and a coil group 92 is wound around the magnetic pole piece group 91. The coil group 92 is electrically connected to a circuit board 93 with a vent hole 931, and is covered with epoxy resin 94 and other sealing glue covers the magnetic pole piece group 91, the coil group 92 and the circuit board 93 to form a closed and integrated stator structure, so that the existing glue-sealed stator 9 has a waterproof and moisture-proof effect. An embodiment similar to the above-mentioned sealed stator 9 is disclosed in the Chinese invention patent No. 201010503545.6 "Fan Motor". [0003] Also, please refer to figure 2 As shown, in the process of coating the epoxy resin 94 in the above-mentioned exist...
