e-motors

Although it will still take several years before Hybrid Cars and Electrical Vehicles will be produced in substantial numbers, today Envalior is already cooperating with various customers in the automotive industry in order to find the best solutions for various applications including: - start/stop components (such as starter gears and solenoids and alternator bearings, covers and bobbins in Stanyl PA46) - coil insulation for electromotors (in Stanyl PA46) - High Voltage cables (in Arnitel TPC) - High Voltage connectors (in Arnite PBT) or High Voltage charging plugs (in Akulon PA6) - Structural parts and body panels (in thermoplastics or thermosets) Some of these solutions are described below in more details.

Coil Insulation of E-Motors

Due to the high temperatures in the E-motors, the coil insulation requires the use of high temperature resistant materials such as PA46, PPA or PPS. Stanyl PA46 offers excellent part performance and the lowest potential system costs thanks to a potential wall thickness reduction of 20-40% - which will also lead to lower induction voltage peaks, as well as easier processing compared to PPS and PPA. This has already been demonstrated for coil insulations in electrical water pumps and oil pumps, where Stanyl PA46 has become the material of choice
