Electric motors are driving the transport revolution
Groundbreaking power densities and harsh operating conditions require a new approach to electric motors
Over 30% of electric motor failures stem from overheating insulation
These overheating problems are a major limiting factor in better motor design and performance
This problem is made worse by legacy thermal classes that overstate the high temperature performance of insulation
FAC Technology is solving the overheating problem with resins designed for maximum robustness at high-temperature.
This includes a series of high-performance resins for impregnation, encapsulation and potting of electric motors and power electronics. FAC Technology resins exhibit glass transition temperatures (Tg) up to 220°C. FAC Technology materials boast unparalleled durability and crack resistance at this Tg level, enabling high-temperature motor operation without compromising various electrical and mechanical properties that typically degrade above the Tg.
Case study:
Adhesion to PEEK
FAC Technology is excited to showcase its breakthrough PEEK-compatible resins, designed to ensure optimal performance and adhesion under extreme motor operating conditions.
-
PEEK-coated wires are excellent for supporting higher voltages, but they present a significant bonding challenge
-
Motor designers have reported resin debonding from PEEK under typical motor operating conditions
-
Debonding leads to insulation breakdown and motor failure
FAC Technology has conducted extensive testing and development and can now offer resins that solve this debonding problem
Competitor resins lose 85% of their adhesion to PEEK under motor operating conditions, while FAC Technology resins lose no adhesion
*Competitor resin has been nominated as PEEK compatible and is advertised as thermal class H (180°C).
Testing conducted by FAC Technology using facilities at Imperial College London
