BEST ELECTRIC MACHINE

2. WHAT IS MARKET FOCUS?ELECTRIC MOTORS AND GENERATORS • Electric Motors And Generators are known as Electric Machines: • Consume a majority of all electricity produced; • Produce virtually all electricity consumed; • Collaborative Essentials for virtually any energy efficiency, smart grid, electric vehicle, alternative energy, or renewable energy technology. • Electric Machines are the backbone of the Electricity infrastructure: • Electricity is expected to grow 40% by 2025. • Electronic control of electric machines: • Significantly improves system performance; • Essential for functional operation of state-of-art electric machines. Electric Machines have strategic national and global energy importance!

3. WHAT IS THE COMPETITION?HIGH PERFORMANCE PERMANENT MAGNET ELECTRIC MACHINES • Perceived as the most efficient and most powerful electric machine system available: • Biased by years of investment by industry, academia, and governments (such as the US Department of Energy or DOE); • In reality, all electric machines are similarly sized for a given rating without a fundamental difference in operating principles. • Permanent Magnets consume no power and dissipate no loss. • No brush-slip-ring assembly (some say maintenance free). • Electronic control is essential for practical operation: • Electronic efficiency, cost, and size must be included in performance calculations, which negate perceptions. In Our Quest For Sustainable Energy, PM Electric Machine Systems are quickly taking market share from conventional systems!

4. WHAT IS THE PROBLEM?HIGH PERFORMANCE PERMANENT MAGNET ELECTRIC MACHINES: MATERIAL • High performance PM material is virtually indigenous to China: • China absorbed 90% of the PM supply chain within this decade. • Global supply of high performance PM material cannot meet the anticipated demand for PM electric machines: • http://www.businessmirror.com.ph/home/science/12375-rare-metals-could-trigger-next-trade-war.html In our quest for energy efficiency, will the PM material cartel replace the oil cartel?

5. IS THERE A POTENTIAL ALTERNATIVE?YES: WOUND-ROTORDOUBLY-FEDELECTRIC MACHINE SYSTEM[WRDF-EMS] • Only electric machine with rotor real-estate actively participating in the energy conversion process: • Sure metric for high efficiency, low cost, and small size; • Shows twice the power for a given torque, frequency and voltage of operation: • Theoretically, half the physical size, half the electrical loss, and half the cost for a given power rating. • Only rotor power is electronically controlled for full system control: • Half or Less of Total System Power; • Another level of higher efficiency, lower size, and lower cost. The WRDF-EMS Has Two Fundamental Differences In Operating Principles!

6. BUT WRDF-EMS HAS PROBLEMS!WHY:UNSTABLE AND UNRELIABLE • Unstable Over A Useful Speed Range: • State-of-art Field Oriented Control unsatisfactory for stability; • Stable Control requires transformational technology. • Unreliable, High Maintenance, And Mechanically Complex: • Incorporates a multiphase slip-ring-brush assembly; • Brushless operation requires transformational technology. • Operates Asynchronously: • Relies on speed base induction at most speeds; • Discontinuous about synchronous speed; • Higher electrical losses and larger size. Convinced By Years of Unsuccessful Research: Experts Consider A Brushless, Fully Synchronous and Stable WRDF-EMS Impractical!

7. WHAT IS THE SOLUTION?OnlyBRUSHLESS, SYNCHRONOUS, and STABLEWRDF-EMS[BSS-WRDF-EMS] • Patented with Patents Pending: • Factor Higher Torque Potential of Any Electric Machine; • Up to eight times higher. • Doubly-Fed With No Slip-ring-brush Assembly (i.e., Maintenance Free); • Rock Solid Stability with Synchronous Operation At Any Speed: • Transformational Technology: Real Time Emulation Control. • No Exotic Materials, Such As Permanent Magnets with persistent fields: • Lower cost; • No safety or handling issues; • Field Weakening for electronic reliability but without additional windings with electrical loss. • Inherent Leading, Lagging, or Unity Power Factor Adjustment: • Neutralizes effect of magnetizing current. • Inherent Fault Tolerance and Exceptional Power Quality; • Half the Size of Permanent Magnet (PM) Electric Machines; • Half the Cost of PM Electric Machines; • Half the Electrical Loss of PM Electric Machines: • http://www.bestelectricmachine.com/table-1.htm

8. BSS-WRDF-EMS ENDORSEMENT?US DEPARETMENT OF ENERGY (DOE) • DOE continues to invest ($$$ and years) On Its Internal Project, The Hybrid-Secondary-Uncluttered Induction Machine (HSU-I): • DOE considers HSUI transformational technology: • http://www1.eere.energy.gov/vehiclesandfuels/pdfs/merit_review_2008/adv_power_electronics/merit08_marlino_2.pdf • HSUI is a Brushless but “Asynchronous” WRDF-EMS: • Topology Almost similar to the BSS-WRDF-EMS: • But without proprietary Real Time Emulation control for stability and synchronous operation at any speed; • HSUI has yet to see commercial success: • Has discontinuous control (i.e., unstable): • Induction ceases to exist at synchronous speed; • Has high losses: • “Induction” Doubly-Fed. • http://www.ornl.gov/~webworks/cpr/pres/106286.pdf Inventor of BSS-WRDF-EMS experimented with this concept decades ago and found the only successful approach is the BSS-WRDF-EMS.
