Patent CA-2198824-A1 (CA)
Title: Dc generator
Inventor: MURRAY DAVID
IPC: H02K1/14
Filed: 1997-02-28
Abstract: An improved permanent magnet DC generator includes at  least  one  stator arranged normal  to  a  rotor. Preferably,  there are a plurality of stators each having  successive  strata  of  windings  in  a  first direction, windings in a second direction, and a core comprising  a  surrounding  sheet  of  magnetizable material.   The windings and core are separated by electrical insulation.  The stator may be constructed to include recurring patterns of windings and cores as described above,  all windings being formed from a continuous  conductive  filament.     A  stator  is preferably includes a non-conductive base attachable to the generator by threaded fasteners.   The rotor includes  a  pair  of  diametrically  opposed  magnet groups.  Within each group, there is a leading magnet, a plurality of central magnets, and a trailing magnet. Individual magnets are arranged such that the forward face of the leading magnet,  the outer face of the central magnets, and the rear face of the trailing magnet  all  expose  like  poles  to  the  stator.   A consistent magnetic orientation is thus imposed upon the stator, and parasitic internal losses are thus avoided.   The magnets project rearwardly from the rotor,  and  partly  overlap  or  surround the  motor driving the rotor.  This helps stabilize the rotor at high rotational speeds.  The rotor is potted in epoxy and banded circumferentially with wire to help retain the magnets in place at high rotational speeds.
