Abstract
A flux-regulated permanent magnet machine (PMM) includes a stationary portion and a rotating portion. The stationary portion includes a plurality of stator/armature windings. The rotating portion includes a plurality of permanent magnets and a control/field winding that is supplied with current to control the magnetic flux presented to the stator/armature windings.
Claims27
An flux-regulated permanent magnet machine (PMM) comprising:
- a stationary portion that includes armature windings;
- and
- a rotating portion that includes a plurality of permanent magnets and a control winding that is supplied with current to control magnetic flux presented to the armature windings.
A motor/generator comprising:
- a passive permanent magnet machine (PMM) that includes a stationary portion that includes a first plurality of permanent magnets and a rotating portion that includes a rotating exciter windings that develops an alternating current (AC) voltage in response to the first plurality of permanent magnets;
- a rotating rectifier that rectifies the AC voltage developed in the rotating exciter windings to a direct current (DC) voltage;
- and
- a flux-regulated permanent magnet machine (PMM) that includes a stationary portion that includes stator armature windings and a rotating portion that includes a plurality of permanent magnets and a control winding that is selectively supplied with current to control magnetic flux presented to the stator armature windings.
