Abstract
A permanent magnet motor is provided with a housing, a rotating shaft supported within the housing, and magnetic coils arranged within the housing. A hydrostatic bearing is disposed on the rotating shaft, the hydrostatic bearing having a permanent magnet incorporated therewith that restricts movement of the rotating shaft in a radial direction.
Claims16
A permanent magnet motor/generator comprising:
- a housing;
- a rotating shaft supported within the housing;
- and
- a hydrostatic bearing disposed on the rotating shaft and within the housing, the hydrostatic bearing comprising a first face that is a permanent magnet and a second face that is coils, the first face and the second face arranged such that movement of the rotating shaft is restricted in a radial direction, whereby the permanent magnet and the coils are configured to generate electricity or create force.
1 more element
A method for making a permanent magnet motor or generator, the method comprising:
- providing a housing with a rotating shaft supported therein;
- disposing a hydrostatic bearing on the rotating shaft and within the housing, the hydrostatic bearing comprising a first face that is a permanent magnet and a second face that is coils, the first face and the second face arranged such that movement of the rotating shaft is restricted in a radial direction, whereby the permanent magnet and the coils are configured to generate electricity or create force.
A permanent magnet motor or generator comprising:
- a permanent magnet used as a restrictive element of a hydrostatic bearing;
- coils, wherein the hydrostatic bearing works directly between the permanent magnet and the coils and the permanent magnet and coils are configured to generate electricity or create force.
