Double Air Gap Technology

The electric rotor is characterised by minimal inertia, high revs and high torque. An air gap between the rotor, on one side, and the stator, on the other, means it can be used as an internal and external rotor. The innovative drive system is widely used in Integrated Braking Systems (IBS), Electric Power Steering (EPS), actuators for dual clutch transmission, active damping systems and active rear axle steering.

Double Air Gap Technology

Die elektrische Drehfeldmaschine zeichet sich aus durch geringe Trägheitsmasse für hohe Drehzahlen und großem Drehmoment. Mit jeweils einem Luftspalt zwischen dem Rotor einerseits und dem Stator andererseits können die Motoren als Innen- und Aussenläufer ausgeführt werden. Die innovativen Antriebe finden breite Anwendung in integrierten Bremssystemen (IBS), Electric Power Steering (EPS), Aktoren für Doppelkupplungsgetriebe, aktive Dämpfersysteme und aktive Hinterachslenkung.
