Latest Patents

One of Epstein's latest inventions is a high efficiency permanent magnet machine. This machine is designed to maintain high power density while operating over a wide range of power outputs. Its improved efficiency is attributed to the use of copper wires with lower current density than traditional designs, as well as larger permanent magnets and a larger air gap. The design incorporates wide stator teeth to reduce magnetic saturation, resulting in lower current consumption. Additionally, the machine features a smaller torque angle compared to traditional designs, enhancing its overload handling capability and overall efficiency. When utilized as a motor, it employs an adaptive phase lag compensation scheme that improves the accuracy of the sensorless field-oriented control (FOC) system.

Another significant patent is for a vertical axis wind turbine equipped with cambered airfoil blades. This innovative wind turbine design allows the blades to rotate in a horizontal plane around a vertical axis. The turbine's output shaft is directly connected to the driven shaft of a permanent magnet generator via one-way bearings, eliminating the need for a gearbox and inverters. The design further reduces friction losses by using magnetic bearings to suspend the vertical shaft. The airfoils are strategically positioned to cup the wind on a lower concave portion, enabling self-starting capabilities. Additionally, stealth radar-absorbing mesh and faceted mounting structures are incorporated to minimize radar return scrambling.
