Abstract :
This paper looks into the mechanical and electromagnetic design for rotors with embedded magnets of permanent-magnet-synchronous machines. In a study it has been investigated in which way a solid bridge between the permanent magnets improves the mechanical stability of the system and if it has an influence on the electromagnetic performance. In the second part a new design process for the rotor is introduced. The aim of this design process is to decouple the calculation of the reluctance torque from the permanent magnet torque and to reduce the complexity of the electromagnetic design for the rotor.
