Description

Technical Field

[0001] The utility model relates to the technical field of electric motor production, in particular to a paint dipping device for electric motor production. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and acts on the rotor to form a magneto-electromotive force to generate a rotating torque. During the production process of the electric motor, the coil of the motor needs to be dipped in paint. This will improve the insulation strength and heat resistance of the coil after dipping in paint.

[0003] The varnishing system used in electric motor production requires two steps. The first step is to penetrate the interior of the winding with varnish and fill the pores. The second varnishing process aims to bond the insulation layer to the conductor, further fill the gaps and micropores left by the solvent evaporation during the first varnishing process, and form a protective outer layer on the inner surface of the winding. Therefore, two varnishes with different viscosities are required. However, existing varnishing systems can only varnish the coil once, and after completion, the coil must be moved to the next varnish tank, which affects varnishing efficiency and increases the workload. Therefore, it is necessary to provide a varnishing system for electric motor production that reduces the workload of varnishing. Utility Model Content
