LaunchPoint 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 motor produces 7 horsepower at 8400 rpm with 95 percent efficiency. At 5 horsepower per pound, this motor has a higher power density than any other 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.
LaunchPoint received initial development funding through a Phase I Small Business Innovation Research (SBIR) grant from the Defense Advanced Research Projects Agency (DARPA). DARPA is interested in using the motor in electrically-propelled Unmanned Aerial Vehicles (UAVs).
Although the current design is only 6 inches in diameter and less than 1 inch thick, this high power density motor design can be scaled and adapted for larger applications such as:
- Larger electrically-powered and hybrid Unmanned Aerial Vehicles (UAVs)
- Electrically-propelled manned aircraft and underwater vehicles
- Wheel motors in automobiles and motorcycles
- Wheel motors for scooters, bicycles, and other lightweight transportation devices
The light weight and high power density provided by this new motor design enable:
- Extended battery life
- Longer ranges
- Larger payloads
Continuing development funding is being sought from NASA and the Department of Defense as well as private investors. Several defense manufacturers and multiple branches of the US military have recently expressed specific interest in this motor design. The LaunchPoint Halbach array electric motor, with its ideal combination of power, efficiency and light weight, offers the best solution for applications where performance is critical.
