QM Power and University of Kentucky demonstrate 50 kW/liter electric motor; DOE 2025 power density goal

Green Car Congress

The PM-free castellated rotor, modular stator, segmented PMs, and concentrated toroidal windings are the key features. In addition, since both the PMs and armature windings are placed on the stator and there is no overlapping between them, the design and implementation of the cooling system are simplified. —Madhav Manjrekar.
