Description

Coil injection molding stator assembly Technical Field The utility model relates to the technical field of coil stators, in particular to a coil injection molding stator assembly. Background A coil winder is an end device for an air conditioning system, mainly for adjusting the temperature and humidity of indoor air. The air is forced to flow through the coil pipe (cold water or hot water flows in the air conditioner) by the fan, so that the air is cooled or heated, and the comfort of the indoor environment is maintained. The coiler is generally composed of a fan, a coil, a motor, a control system, and the like. The existing coiler has many problems in practical application, namely, more main bodies are needed to be used by a motor when the installation position of a customer is longer, the cost and the space occupation are increased, the conventional coiler adopts a mode of conducting a BB cover at a position 2 by sticking an electrical adhesive tape, so that production equipment is expensive and the production efficiency is low, and part of motor models lack of stator core positioning structures, so that the stator core position is moved when injection molding materials are stamped, the production assembly is affected, noise is generated, and the performance is abnormal.
