U. Rieder, M. Schrödl:
"Design Optimization of External Rotor Permanent Magnet Synchronous Machines with Respect to Enhanced INFORM-Capability for Sensorless Control";
Talk: PCIM, Nürnberg, Deutschland; 05-25-2004 - 05-27-2004; in: "Proceedings of the International Conference Power Electronics Intelligent Motion Power Quality", (2004), ISBN: 3-928643-39-8; 716 - 720.

In many applications like traction,
starter generators and direct drives the need for
high torque is the basic issue. The paper
presents the combination of advantages of
external rotor permanent magnet synchronous
machines and sensorless control algorithms,
especially for low speed and standstill using the
INFORM-method. Therefore saliency and
saturation effects have to be taken into account
and have been enforced for improved INFORM
performance.
