Essex Magnet Wire is introducing a new, high-temperature rated insulation system for the windings of traction motors utilized in hybrid electric vehicles, plug-in hybrid electric vehicles, as well as electric vehicles: EnduroTemp 260+.
EnduroTemp 260+ is a thin film insulation that will extend the life of traction motors in critical transportation applications and has been specifically designed to withstand higher operating temperatures with an industry best 265 ˚C thermal endurance. The product will also provide protection to the motor against deterioration created by the modern power electronics controlling the motor.
Matthew Leach, Vice President of Innovation and Head of the Essex MagForceX Innovation Center, said that the product is the latest in the line of development for the EV market.
EnduroTemp 260+ is the very type of disruptive technology that we are looking to develop to help the magnet wire industry continue to evolve. Being able to increase the temperature threshold without sacrificing performance—in fact, helping to increase it—is something that is very exciting for our team.—Matthew Leach
Technological advancements being made to increase the efficiency of electric driven vehicles as well as elevated performance requirements of the traction motors and generators is making deterioration exponentially more severe.
Designers have been forced to utilize power electronic speed control with higher voltages and faster switching frequencies to drive the motors which puts severe stress on the windings of a motor. Where EnduroTemp 260+ thrives is where typical winding insulation utilized for standard motors will fail under similar conditions in only a few hours, the company claims.
Essex Magnet Wire has been a pioneer of inverter duty winding or magnet wire. The company has more than a quarter century of nano-technology experience.
The Essex MagForceX Innovation Center has a dedicated team of scientists and engineers exploring technologies impacting magnet wire that are available to engage with outside corporations. The Center is testing and innovating thermosets, thermoplastics, and additives as well as focusing on conductor processing and fabrication processes.
The knowledge accumulated was utilized to develop this new magnet wire designed to resist the effects of modern power electronics for electric vehicles.
Essex Magnet Wire has facilities in 11 countries on three continents.
