A kind of anti-rust method of stator and rotor iron core

Abstract

The invention discloses a method for rust protection of stator and rotor cores. Epoxy resin paint is sprayed on the surfaces of stator and rotor cores to be subjected to rust-proof treatment, and then solidification treatment is performed. Since the epoxy resin paint and impregnating varnish belong to paint of the same kind, and through experimental verification, a chemical reaction does not occur, cleaning of antirust paint is avoided, thereby greatly lowering the operation difficulty of rust-proof treatment, and improving the operability of a rust-proof treatment method for the stator and rotor cores.

Description

Technical field [0001] The invention relates to the technical field of stator and rotor manufacturing, in particular to a method for preventing rust of stator and rotor cores. Background technique [0002] At present, for the rust prevention of the finished stator and rotor cores in storage, the rust prevention method usually used is weather rustproof paper for packaging and sealing. However, the rust prevention process cannot solve the problem of rust prevention during the processing and production of the stator and rotor cores, especially large ones. The stator and rotor cores of medium-sized motors have a long production cycle during process flow and processing. During this process, if anti-rust measures are not taken, the surface of the core is prone to rust. [0003] For rust prevention in the production process, the general rust prevention process is to spray ordinary iron-based rust inhibitors for rust prevention. However, since the general stator and rotor cores need to be ...

Problems solved by technology

[0002] At present, for the rust prevention of the stored finished stator and rotor cores, the rust prevention method usually used is weather antirust paper for packaging and sealing, but this antirust process cannot solve the rust prevention problem of the stator and rotor cores during processing and production, especially for large The stator and rotor cores of medium-sized motors have a long production cycle in the process of process flow and processing. If no anti-rust measures are taken during this process, the surface of the core is prone to rust

[0003] For the anti-rust in the production process, the common anti-rust process is to spray common iron-based anti-rust agent for anti-rust, but because the general stator and rotor cores need to be insulated after the wire is embedded, and the iron-based anti-rust agent is easy to mix with The impregnating varnish of the polyimide insulation system and the impregnating varnish of the epoxy anhydride insulation system (hereinafter referred to as the impregnating varnish) react, so the stator and rotor after the wire embedding should clean the antirust agent on the iron core before impregnating the varnish. However, since the iron core groove cannot be cleaned because of the embedded coil after the iron core is embedded, the exposed iron core surface is difficult to clean due to the need to prevent the cleaning agent from penetrating into the coil and the cleaning surface is large. The process is poor in operability, and it is time-consuming and easy to cause quality problems in actual operation

[0004] In summary, how to solve the problem of poor operability of the antirust treatment method for stator and rotor cores has become a technical problem to be solved urgently by those skilled in the art
