Impregnation of electric motors
Impregnation technology
bdtronic offers customized impregnation solutions for electric motor production.
High quality in series production
Impregnation technology is needed in the production of electric drives, both for hybrid technology and for fully electric drives for cars and trucks. During impregnation, the cavities between wires are closed and sealed. This provides better electrical insulation and prevents vibration. Impregnation increases thermal conductivity and contributes to a better environmental balance.
Optimal production lines
Process quality
When resin is applied to a stator or rotor, the right quantity and with the right curing and gelling conditions are key. The resin, machine and process parameters need to be in optimal harmony. Therefore our Technology Center has all needed testing and analysis options, to develop the optimal impregnation processes for serial production. Take advantage of our many years of experience in processing electric motors.
The result is a fully automatic production line with full process control for high quality stators and rotors which include shortest cycle times with the lowest TCO, optimum machine layouts and result in clean impregnation results.
Increased durability
Clever Thermal Management
Heat management is vital for impregnating motors and powder coating welds. By carefully managing heat distribution for both stators and the varnish, we ensure uniform resin flow and superior insulation properties.
Similarly, powder coating the welds of hairpin stators demands meticulous attention to heat management. Effective temperature regulation guarantees a flawless coating application, resulting in enhanced durability and resistance to environmental factors, even on complex designs. Proper thermal management results in optimal insulation, flawless coating and increased durability.
High performing motors
Best filling grades - 99% plus
A high filling grade is required to reduce the risk of partial discharges. With the right equipment and process control in place a trickling varnish process results in similar filling grades as a conventional dipping process.
Get the best performance for motors of electric and hybrid vehicles.
