Santa Barbara, CA ( PRWEB ) September 21, 2009 -- LaunchPoint Technologies, Inc. has completed optimization and initial prototyping for a high efficiency, high power density, Halbach array electric motor . With a total weight of only 1.4 pounds, this electric motor produces 7 horsepower at 8400 rpm with 95 percent efficiency. At 5 horsepower per pound, this electric motor has a higher power density than any other electric motor on the market. The brushless, axial flux permanent magnet design is highly tolerant of temperature and centrifugal effects, and the ironless rotor and stator eliminate iron eddy current and hysteresis losses.

Although the current design is only 6 inches in diameter and less than 1 inch thick, this high power density electric motor design can be scaled and adapted for larger electric vehicle motor applications such as: electrically-powered and hybrid UAVs; electrically-propelled manned aircraft and underwater vehicles; wheel motors for automobiles and motorcycles; and wheel motors for scooters, bicycles, and other lightweight transportation devices.

Designed and developed by LaunchPoint Senior Systems Engineer, Geoff Long, the new high efficiency electric motor will enable applications not previously possible. With the move to electrically-powered vehicles of all types, LaunchPoint's motor technology is timely. "Highly efficient and lightweight electric motors are needed now more than ever, and that's exactly what LaunchPoint's technology delivers," notes Long. "LaunchPoint's electric motor technology squeezes more power out of a smaller package and at a higher efficiency than any other motor on the market."

AC Contactor: An alternating current (ac) contactor is designed for the specific purpose of establishing or interrupting an AC power circuit.

Accelerating Torque: The torque developed from standstill (zero speed) to full speed at nameplate voltage. Sometimes the term "Net Accelerating Torque" is used to mean the excess motor torque capability over the torque for the attached load.

Adjustable Speed Drive: A unit comprised of a motor, drive controller and operator’s controls (either manual or automatic). Is also used to refer to the inverter which is a device used to convert standard sine wave power form into a simulated form for varying speed ranges on the driven equipment.
