Abstract
A permanent magnet generator is described. The generator includes a shaft which defines a longitudinal axis. A rotatable magnetic field assembly is mounted on the shaft and adapted for rotation about the shaft. The magnetic field assembly includes a plurality of axially magnetized magnets which are retained in a cavity about the shaft for generating an axial magnetic flux. A plurality of vanes are mounted on the magnetic field assembly housing for rotating the magnetic field assembly about the shaft when a fluid flows past the vanes. A stationary armature assembly is also located around the shaft in a position axially spaced from the magnetic field assembly. The armature assembly generates AC power when the magnetic field assembly is rotated. The stationary armature assembly includes an armature housing. An axial bore is formed through the armature housing for receiving the shaft. The armature housing defines a cavity about the axial bore in which a plurality of laminated bars are retained. A plurality of electrically conductive wires are wrapped around the laminated bars to form coils.
