I had contact with Sterling and later Elantas for many years. There were several joint projects, but the cooperation was interrupted after the motors production was taken over by the Middle Kingdom. I regret that the tests of motor windings adapted to be powered by inverters have not been completed. The problem was to completely remove the air bubbles in the cured resin. There is also a prospect of introducing mineral components into the impregnation resin (stable suspension) in order to improve the thermal conductivity of the resin. It is known that better heat dissipation from the winding reduces its temperature, which in turn causes lower electrical resistance, which translates into greater motor efficiency. I had a little laugh when I saw the wound stator of the motor without the wires feeding the winding. I know these are tests, but they're a bit impractical.
Hello Jozef, thank you for your comment. We are usually not allowed to show details of components of our customers in our videos, so we improvise, to demonstrate our technologies. For each project we test and define the parameters in our Technology Center to avoid air bubbles and get the best results. We can provide roll-dipping but also trickle varnishing solutions and the parameters also differ depending on which resin should be used. You can have a look on our Website about the process development in our technology center here: www.bdtronic.com/en-en/technology-center/technology-center-impregnation/ Best Regards Regina, bdtronic Marketing
For the video we have used a sample stator without connections. Depending on how the stator is constructed, the suitable impregnation method is selected. For the roll-dip method, the connections must be fixed in the middle of the stator.

Where is the connecting lead. How do you protect it from varnish get deposit on lead?

omg, you guys are so rich.
those equipments need to cost a lot of money.
damn~~
