SYNCHRONOUS MACHINE WITH OPTIMIZED EXCITATION DEVICE FIXED TO THE STATOR

SYNCHRONOUS MACHINE WITH OPTIMIZED EXCITATION DEVICE FIXED TO THE STATOR

A synchronous machine has a rotor rotatable about an axis of rotation and a stator surrounding the rotor radially on the outside. When viewed in axial direction, the rotor has a number of rotor rings running tangentially around the axis of rotation. When viewed in tangential direction about the axis...

description A synchronous machine has a rotor rotatable about an axis of rotation and a stator surrounding the rotor radially on the outside. When viewed in axial direction, the rotor has a number of rotor rings running tangentially around the axis of rotation. When viewed in tangential direction about the axis of rotation, the rotor rings each have a plurality of claws of soft-magnetic material. The claws are in the form of an L, defined by first and second limbs. An excitation device is fixed to the stator and has, for each rotor ring, a magnetic field generator which interacts with the respective rotor ring and is arranged radially inside the respective rotor ring. The magnetic field generator generates a magnetic field directed in the axial direction and is coupled magnetically to the second limb of the claws of the respective rotor ring in the region of the radially inner termination.
