Find out which materials can be used in your eDrive motors
The automotive market is in a state of upheaval; electromobility is on the rise around the world. While a 12-volt battery used to be the standard in vehicles, future drivetrains will be equipped with 800 volts and more. Because of this, the voltage on board a vehicle can reach a level where discharges and partial discharges can occur. Without proper insulation, this could destroy the motor.
Leading system for high-voltage stress
We work with OEMs, suppliers, and motor manufacturers to test which resistant materials can be used for their products based on their specific requirements. Our system for high-frequency high-voltage stress is one of the world’s leading systems of its kind.
We test motors under inverter conditions. A frequency converter converts pressure on the gas pedal into electrical impulses. This exposes the insulation material to significantly higher voltages, a higher frequency and increased temperatures. At the end, you receive a test report and recommendations for your insulation system.
Von Roll has over 100 years of high-voltage expertise. This is why leading pioneers in electromobility trust in us.
