Abstract
The invention relates to electric machines having permanent excitation, having a very high specific torque and a high power density when correspondingly supplied through power electronics. They are characterized by advantageous production possibilities using composite materials that can be pressed in molds. The nonferrous rotor construction and low required magnet mass results in an extremely low moment of inertia.
