Key Facts
PSM-level performance580 Nm, 325 kW. Plugged coils feature high efficiency, torque & power densityCompact & fully integrated90 mm reduced axial length, no sealings compared to state-of-the-art ESMsSustainableInductively excited rotor coils w/o magnets hence w/o rare earth elements
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 - and is on eye-level with permanent-magnet synchronous machines.
