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.

Description

[0001] Cross References to Related Applications [0002] This application is a Continuation in Part (CIP) of US Patent Application Serial No. 14 / 792,799, filed July 7, 2015. technical field [0003] The present invention relates generally to electromagnetic machines, and more particularly to multi-degree-of-freedom electromagnetic machines, such as motors and / or generators. Background technique [0004] It is generally known that currently available motion control systems designed to move objects in more than one degree of freedom (DoF) include separate motors or actuators for each DoF. More specifically, at least two motors or actuators are required to effect a 2 DoF movement, at least three motors or actuators are required to effect a 3 DoF movement, and so on. Consequently, mechanisms involving more than one DoF tend to be somewhat large and bulky, and thus inefficient. [0005] While electronics and sensor technology have become significantly smaller in recent years, m...
