Abstract
The object of the invention is to provide a generator easy to assemble even if there is an obstacle such as a turbine in the axial direction of the rotor of the generator. A generator comprising; a rotor having a permanent magnet placed therein and supported to be rotatable, and a stator having a field coil wound thereon, characterized in that; the rotor is provided with a seating made of a magnetic material for supporting the permanent magnet and a pole shoe made of a magnetic material placed in the outward radial direction of the permanent magnet.

A generator comprising;
- a rotor having a permanent magnet placed therein and supported to be rotatable, and a stator having a field coil wound thereon, characterized in that;
- the rotor is provided with a seating made of a magnetic material for supporting the permanent magnet and a pole shoe made of a magnetic material placed in the outward radial direction of the permanent magnet.
A generator comprising,
- a rotor having a permanent magnet placed therein and supported to be rotatable, a stator having a field coil wound thereon, the rotor is provided with a seating for supporting the permanent magnet, characterized in that;
- the radius of the arc part of the pole shoe is smaller than the radius of the rotor.
An electric generating system comprising;
- a rotor having a permanent magnet placed therein and supported to be rotatable, and a stator having a field coil wound thereon, characterized in that;
- the rotor is provided with a seating made of a magnetic material for supporting the permanent magnet and a pole shoe made of a magnetic material placed in the outward radial direction of the permanent magnet, and that the rotor is rotated owing to the rotating force applied by a turbine.
An Electric Generating System comprising;
- a gererator, an exciter and a coupling,
- characterized in that;
- the exciter is installed between the coupling and a rotor shaft of the generator.
