FAQ
We have systems ranging all the way to 1.6 w/mk. While we are aware that there are motor potting systems with higher ratings than this, we find that anything above 1.6 is quickly reaching diminishing returns. We have found this to be the high-end sweet spot, where materials can still penetrate windings and deliver efficient thermal transfer.
The two most common reasons include enhancing performance and protection from elements. Many wash-down duty motors are encapsulated to guarantee long-term performance in harsh environments. Many high performance motors are encapsulated to increase the ability of the motor to move heat out of the windings, increasing efficiency and performance.
Most of our motor potting systems are low viscosity, especially when preheated. In many cases, the dispensing process will include a vacuum process to ensure a full, airless dispense.
EFI has several ways to help. In the trial phase, it may be possible to test using hand-mixing and vacuum pot. Or EFI can enlist the help of one of our dispense machine partners. When it comes to production, EFI has close partnerships with several meter-mix dispense machines, who we will work closely with to help design your process.
