Motor dipping control determines the life of the motor to some extent
Dipping paint is a very special and critical part of the motor manufacturing process. The particularity of the dip coating process lies in the fact that this process deals with inflammable and explosive chemicals, which has serious safety hazards and outstanding environmental protection problems.
Speaking of the key to the dip coating process, you may wish to review MS. It can be said that there are too many topics related to motor insulation in MS. The insulation is the life gate of the motor, the insulation system of the special special motor, the influence of the insulation on the temperature rise of the motor, etc., and it is almost impossible to add. Therefore, it is not difficult to understand that the winding immersion paint is too critical for a motor. Each motor manufacturer will always spend huge sums of money to continuously update the motor immersion equipment.
MS. Participate in the comparison of stator windings after dismantling of motor products from well-known motor manufacturers at home and abroad. Some windings have a thick layer of paint deposited on them, while others look particularly thin. Manufacturers have different manufacturing processes and equipment. Based on the analysis of the appearances, the colleagues have different opinions and opinions. However, the analysis from different angles makes MS. The feelings are quite deep. After all, it is impossible to find any agreement with the facts. The winding gap is sufficiently dense to be filled with paint to be considered as a good quality product.
The total effect of the immersion paint is directly related to the core components of the motor – the reliability of the windings, the impregnating varnish and the immersion lacquering process equipment are the necessary hardware conditions to ensure the advanced level of the motor manufacturing. In order to participate in the discussion of the effects of insulating impregnating varnish and winding dip coating, today Ms. will put forward some of his own views and insights in order to explore and study special technical topics in a deeper level.
Edge dipping paint
Insulating impregnating varnish is one of the main insulating materials of electric motors. It is mainly used for impregnating motor stator and rotor windings, and is divided into solvent-free paint and solvent paint. The impregnating varnish fills the air gap between the motor stator, the rotor winding and the inner conductor of the iron core slot and the iron core. Since the immersion paint has better thermal conductivity than air, it can effectively reduce the temperature rise of the motor and prolong the service life of the motor.
Dip drying
The immersion drying is performed by infiltrating the gap between the motor coils of the impregnated varnish and heating and drying. By dipping the insulating varnish, the motor coils are solidified as a whole, reducing and eliminating mutual movement, improving the overall effect of the motor and the ability to withstand moisture and chemical contamination. The performance of the motor is particularly critical and important.
VPI dipping process
VPI dipping is the abbreviation of VacuumPressureImpregnating in vacuum pressure dipping. The process is divided into two stages: vacuuming and pressure painting. At present, many motor manufacturers adopt VPI dipping process. Through VPI treatment, the paint liquid can be fully infiltrated and the air in the winding can be evacuated, which effectively improves the electrical strength, mechanical properties, thermal conductivity and protection performance of the motor.
