DYNAX® is a permanent magnet motor with a claw pole stator and axial orientated windings. Its external glass-fiber rotor with thin permanent magnets - a back iron is not necessary - provides a notable high torque and allows extended motor speed. Because of a considerable stray inductance and a low short circuit current, a quasi field weakening operation over a wide range of speed is possible. On the other hand, control and inverter have to manage high fundamental frequencies because of the typically high number of pole pairs. The presented paper shows the advantages especially for electric cars and starter alternators as well as the special demands on the electric motor control.
