Benefits of technology

[0012]In one embodiment the invention is a multi-phase electric motor, comprising a stator comprising a plurality of wire coils surrounding a non-magnetizable core; a rotor with permanent magnets embedded therein, the rotor being disposed adjacent to the stator, the rotor being mounted on a rotatable drive shaft; a power source; a position sensor operably connected to the rotor; and a control circuit operably connected to the power source, the position sensor, and the wire coils, for controlling distribution of electrical energy to the wire coils; wherein the control mechanism transfers electrical charge from a first coil to a second coil. There is provided certain design and spacing conventions between the magnets and coils for optimum performance. Further, the control circuit utilizes pulse modulation in order to enhance control and maximize efficiency.

Problems solved by technology

However, non-magnetizable core materials such as plastics have not been used for high power motors.

Embodiment Construction

[0047]The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

[0048]The motor described herein, which is referred to as a ‘magnetronic’ motor, differs from conventional electric motors in several respects, with the result that typical formulas describing motor behavior do not always apply to the magnetronic motor. This is due to several factors:

[0049]1. A conventional motor output requires steel to concentrate the magnetic flux; and

[0050]2. A conventional motor converts electric force into magnetic flux in the metal components, thereby completing the magnetic circuit through the stator and rotor which generates the torque applied to the rotor.

[0051]Because of these factors the maximum power output of a typical motor is limited by the amount of steel in the field and rotor as well as the amount of copper in the windings.

[0052]The motor described herein differs in these components...

Abstract

A multi-phase electric motor comprises a stator comprising a plurality of wire coils surrounding a non-magnetizable core; a rotor with permanent magnets embedded therein, the rotor being disposed adjacent to the stator, the rotor being mounted on a rotatable drive shaft; a power source; a position sensor operably connected to the rotor; and a control circuit operably connected to the power source, the position sensor, and the wire coils, for controlling distribution of electrical energy to the wire coils. In this motor the control mechanism transfers electrical charge from a first coil to a second coil.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of U.S. patent application Ser. No. 11 / 460,149, filed Jul. 26, 2006.[0002]This application claims priority to provisional application No. 61 / 188,994 filed Aug. 15, 2008.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0003]Not Applicable.APPENDIX[0004]Not Applicable.BACKGROUND OF THE INVENTION[0005]1. Field of the Invention[0006]The present invention relates to electric motors for generating current.[0007]2. Related Art[0008]As energy costs continue to rise and supplies dwindle there is a substantial need for more efficient use of energy, particularly for electric motors. Electric motors power many devices and thus improvements in power output from motors for a given input energy would mean significant savings in energy costs.[0009]One usage in particular that would benefit from an improved electric motor is that of electric wind turbines. Improvements in electric motor power outp...
