Multi-degree of freedom electromagnetic machine
First Claim
1. A multi-degree-of-freedom electromagnetic machine that may be operated as a motor, a generator, or a motor-generator, the machine comprising:
- a first structure comprising a first body, a first conductor, a second conductor, and a third conductor, the first body formed of a magnetically permeable material and having an outer surface, at least a portion of the outer surface having a general shape of a surface, the first conductor following a first general trajectory, the second conductor following a second general trajectory that is different from the first general trajectory, the third conductor following a third general trajectory that is different from the first and second general trajectories, the first, second, and third conductors disposed at least adjacent the portion of the outer surface of the first structure and having the general shape of the surface; and
a second structure disposed adjacent to the first structure and including a magnet that emanates a magnetic field, the magnet having at least one of its magnetic poles facing the surface,wherein a Lorentz force affects relative movement between the first structure and the second structure when the magnetic field that emanates from the at least one magnetic pole interacts with electrical currents within any of the electrical conductors.

Abstract
A multi-degree-of-freedom electromagnetic machine that may be operated as a motor, a generator, or a motor-generator, includes a first structure and a second structure. The first structure comprises a first conductor, a second conductor, and a third conductor, each of which follows a different trajectory. The first, second, and third conductors together form a general shape of a surface. The second structure is disposed adjacent to the first structure and includes a magnet that emanates a magnetic field. The magnet has at least one of its magnetic poles facing the surface. A Lorentz force affects relative movement between the first structure and the second structure when the magnetic field that emanates from the at least one magnetic pole interacts with electrical currents within any of the electrical conductors.
