This however makes highest demands on the functional safety of such drive systems: An incorrect setting of torques generates an undesired yawing torque around the vehicle s vertical axis which is difficult for the driver to control. Permanent magnet synchronous machines often used in current traction applications pose a special challenge: They are normally also operated in the field weakening range in order to obtain constant power ou...

Effects of continuous rotor skewing in additively manufactured permanent magnet rotors authored by Stefan Urbanek, Ralf Keuter, Emma Peter, Bernd Ponick Abstract This paper describes the effects of skewing the rotor of a permanent magnet synchronous machine PMSM with buried magnets by torsion of the soft magnetic rotor active part and maintaining the magnet pockets axially straight.

Numerical and experimental study of liquid metal stirring by rotating permanent magnets authored by V. Dzelme, A. Jakovics, J. Vencels, D. Köppen, E. Baake Abstract In this work, we study liquid gallium stirring by rotating permanent magnets. We demonstrate possibility of easily creating different flow patterns by rotating permanent magnets, which can be industrially important for controlling heat and mass transfer p...
