Manufacturing method of stator

Abstract

The invention discloses a manufacturing method of a stator. The manufacturing method comprises the following steps: an enamelled wire is wound on a stator core, then a lead and / or a circuit board is arranged on a winding formed by the winding of the enamelled wire, and the lead and / or the circuit board is fixed by using an insulated rubber tape to obtain a stator module; a plastic film is wound on the peripheral region of the stator module, and the plastic film extends to the two outer ends of the stator module respectively, then the plastic film is heated by using a heating device to be subjected to plastic deformation so as to form an annular plastic groove wrapping the outer surface of the stator module; and the stator module the outer surface of which is provided with the annular plastic groove is put into a mould and is molded on the periphery of the stator module by injection molding and curing so as to form a main case. As the stator of a plastic package motor is manufactured by the method, the condition that scotch tapes and the stator module need to be bound by utilizing a wire binding machine can be avoided, the operation is simple, convenient and rapid, the production efficiency of the stator is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of plastic-encapsulated motor production, in particular to a method for manufacturing a stator. Background technique [0002] The stator of the AC asynchronous plastic-sealed motor is composed of the stator core, the stator winding, and the casing. The enameled wire is wound into the stator core by a winding machine, and then the circuit board and the lead wire are set on the winding formed by the enameled wire, and the insulating glue is used to Fix the circuit board and lead wires with paper, and then put the stator assembly obtained above into a mold for injection molding of the machine case. After the circuit board and lead wires are fixed, in order to avoid damage to the leaking enameled wire paint film and the circuit board during subsequent operations and to prevent the high temperature during injection molding from loosening the insulating tape and the stator assembly, resulting in waste; therefore, fix the ci...

Problems solved by technology

However, when implementing this method, there are the following disadvantages. First, the efficiency of wrapping the transparent adhesive tape on the periphery of the stator assembly is low, and it is inconvenient to operate; second, it is inconvenient to use a wire binding machine to bind the transparent adhesive tape and the stator assembly. , the pins of the wire binding machine are easy to hurt the workers and the enameled wire, and the working hours required for the binding operation are long
