Description

Technical Field

[0001] The utility model relates to the technical field of motor coil processing, in particular to a coil varnish dipping device used for the production of permanent magnet synchronous motors. Background Art

[0002] A permanent magnet synchronous motor is a motor that works on the principle of electromagnetic induction. It consists of components such as a stator, a rotor, and end covers. It uses permanent magnets to provide excitation, which makes the motor structure simpler, reduces processing and assembly costs, and eliminates collector rings and brushes that are prone to problems, thereby improving the reliability of the motor's operation. Because no excitation current is required and there is no excitation loss, the efficiency and power density of the motor are improved. It has the advantages of small size, simple structure, and high power density, and is widely used in position tracking control systems. The motor coil is the most fragile component in the motor structure. In order to improve the moisture resistance and corrosion resistance and insulation strength of the motor coil, and to improve the mechanical strength, thermal conductivity, heat dissipation effect, and delay aging, the motor coil needs to be dipped in paint.

[0003] The Chinese patent with the authorization announcement number CN218102916U discloses a coil varnishing device for micro-motor production, which can greatly improve the efficiency of the coil varnishing for micro-motor production and shorten the processing time by being able to perform varnishing treatment on the coil for micro-motor production. At the same time, it can effectively avoid the disadvantage that the clamping part cannot be well dipped in the conventional direct clamping coil varnishing process;

[0004] Although the coil can be dipped in paint, the clamping plates need to be opened one by one and the coil is placed on the fork rod when the coil is clamped. This is inefficient when the coil is dipped in paint in batches. Therefore, a coil dip-painting device for permanent magnet synchronous motor production is proposed to solve the above problem.
