Electric Machines for Propulsion
.
LaunchPoint has developed a family of high-efficiency and high specific power electric machines for the demanding, high-reliability applications associated with electric and hybrid electric flight.
Our electric motors and generators are an axial-flux (“pancake”) design based on dual-Halbach-array magnet rotors and ironless stators. This combination of design features allows for an extremely high efficiency motor or generator with good specific power and excellent high-speed efficiency.
The short, disc-like aspect ratio minimizes rotodynamic concerns in high-speed operation and allows the electric machine to use the bearing built into the load, eliminating separate bearings and a shaft coupling when integrated.
The motors and generators are air-cooled and create their own airflow so no additional cooling system or fan is required.
LaunchPoint’s electric machines have patented features that can eliminate most of the common failure modes of permanent magnet machines enabling fail-operational high-reliability applications.
