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 can be air-cooled and create their own airflow so
no additional cooling system or fan is required. Liquid-cooled configurations
are also available depending on the application.

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.
