Critical to materials, the majority of the EV market is using motors with permanent magnet-based rotors. These materials typically contain several rare-earths such as neodymium and dysprosium, both of which have a very geographically constrained supply chain and a volatile price history.
The resin is a perfect electrical insulator and it gives properties absolutely incomparable to other insulating methods: enhanced water and dust resistance, chemical resistance, less vibrations, less noise but most of all a perfect heat dissipation and improved thermal shocks resistance.
the core part of an automobile, motor is expected to have an excellent performance with regard to instantaneous power, power density, overload resistance capacity and product life cycle. The application of insulating material enables a motor to deliver those properties, therefore, allowing EV/HEV automobiles to be used regularly in a demanding environment such as high temperature, high moisture, and salty conditions.
Global EV electric motor epoxy Encapsulant market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Axalta launches Voltacast 3310 – a new epoxy resin in its Energy Solutions portfolio. Axalta, a leading global supplier of liquid and powder coatings, launches Volta Cast 3310/Volta Cast H134, a new epoxy-based casting resin system that expands the Voltacast product portfolio of casting resins from Axalta’s Energy Solutions business.
Voltacast 3310 is specifically designed to offer high thermal stability in combination with high thermal conductivity for winding head encapsulation or total stator encapsulation of electric motors, like servo drives or large machine tools.
“We are always looking to expand our product portfolios and to meet the ever-evolving needs of our customers,” explains Christoph Lomoschitz, Global Product Manager for Axalta’s Energy Solutions business.
“Voltacast 3310 ensures outstanding resistance to a variety of automatic transmission fluid oils used in electric vehicles, and its high thermal conductivity in combination with oil cooling of electric motors allows maximum heat dissipation.”Voltacast 3310/Voltacast H134’s anhydride-free system can be cured at room temperature or preferably at temperatures up to 70ºC.
The cured material is flame retardant, fulfilling the requirements of Underwriters Laboratories (UL) standard 94, class V0, and will shortly receive official UL recognition.
