horus Motors began working on the Chorus® technology in the early 1990s. Jonathan Edelson, a recent graduate of Princeton University, had some novel ideas for motor (and other) technologies, and Borealis supported his research. It was recognized that electric motors are an enormous, if low-profile, industry, with annual sales of many tens of billions of dollars. If something really innovative could be developed, then the potential was very exciting. The goal, then as now, was simple: to fundamentally advance motor technology.

After the electric motor was invented in the 1880s, intensive efforts to improve it began. For several decades, scientists and engineers made many advances in the technology, but by around 1915, motor engineers had achieved technology that was adequate for most purposes, and fundamental development practically ceased. Since 1915, motors have been optimized with better geometries, fabrication methods, and materials. But the underlying principles of AC Induction and DC motors were unchanged and unchanging.

Since the invention of the variable-speed motor in the 1950s, there has been no significant advance in motor science. Motors have been for decades a commercial commodity, generally sold for the lowest price and with little incentive for, or expectation of, significant improvement. Motors which demonstrate higher efficiency do so typically because they use more, higher quality materials, not because they operate in a different way.

Research by governments and universities has been focused on efforts to reduce or eliminate the electromagnetic harmonics created by motors. These harmonics degrade the performance of motors, reducing their power and causing wasteful heating. Motors consume 60% of all electrical power produced, and as energy concerns have increased, the destructive force of motor harmonics has become a more serious problem. Thus most motor research today is aimed at reducing these harmonics.

Chorus' research, led by Mr. Edelson, concluded that motor harmonics cannot be eliminated. But they can be co-opted, or harnessed, into a "chorus" of harmonics that can be redirected to support, rather than harm, the fundamental torque of a motor. And by harnessing and using the harmonics, the Chorus technology enables a motor to achieve significantly greater performance than comparable three-phase AC motors, along with better reliability and reduced maintenance.

The Chorus Star motor is based on this harmonic-using, more-efficient technology. Chorus Star is fundamentally different from three-phase motors because Chorus Star uses more than three phases (typically between 5 and 18), and these phases are arranged and controlled in a different way.

More recently, Chorus' scientists have made another advance, the Meshcon™ drive technology, which enables a motor to achieve very high torque even while operating at very low startup speeds. Chorus' Meshcon technology is probably the most important advance in motor science in a century, and will make electric motors far more useful in far more applications. One example is that Chorus Meshcon will make it possible to replace hydraulics in many applications.

Chorus' scientists continue to make advances in motor-related fields. Yet other technologies in development aim to improve the efficiency of generator sets.

Over the next few years, Chorus aims to make Chorus Star and Chorus Meshcon increasingly common names in the motor and drive sector. Initially, products are being offered directly to customers, though over time licensing revenue should become an important source of revenue for the company.

Chorus Motors plc is a member of the Borealis Family of Companies, and is a majority-owned subsidiary of Borealis Exploration Limited, a technology development holding company. Both companies are publicly owned, and their shares trade on the over-the-counter market in the United states, Chorus under the symbol CHOMF and Borealis under the symbol BOREF.
