I2SM

In-rotor inductive-excited synchronous e-motor

Separately excited synchronous machine

Key Facts

Compact

90 mm reduced axial length compared to current SESM due to integrated exciter

Full integration

No special sealing or dry installation space required

Sustainable

50% reduced CO₂ footprint, no magnets, less materials

Efficient

High power density, high speed, low drag losses

What can I2SM provide?

ZF has developed a separately excited synchronous machine which relies on inductive energy transmission and overcomes the disadvantages of a classic separately excited electric machine. An inductive exciter is installed in the rotor shaft itself. This achieves maximum efficiency and power density in the smallest possible installation space.
