Custom axial flux light weight custom electric motor

Scalable in size and stackable as the power need

Our ultra light permanent magnet brushless DC electric motor technology is an axial flux outrunner and provides higher torque at lesser weight. It can be rapidly tailored to meet your exact specification between 65mm to 425mm in diameter, and the electric motor can be stacked to meet the power requirement from 50W up to 56kW. With each stack, you will add up power and torque to the electric motor.

How Turncircles enable longer flight times for drones

On March 6, 1918, the first unmanned flight successfully traveled 1,000 yards to a predetermined way point. UAVs today are used for inspection, delivering post like never seen before and capturing video from points of views that only birds could enjoy. These UAVs suffer the same issue since 1918: The flight time. Majority of drones today must land after about thirty minutes of flight and they remain grounded until the battery is recharged. If you project UAVs to niches like search and rescue operations, aerial survaillance, and home delivery, then imagine the potential of being able to stay in the air longer. The problem of staying in the air requires innovation. Turncircles is focused on innovative ways to push the flight time status quo to new boundaries by powering drones with composite reinforced motors with the highest power to weight ratio in the industry.

Applications beyond drones

Mainly defined for propeller applications, our electric motors are as well suitable for other applications, sometimes combined with a gear box. E-bikes, wheel chairs, airline cabin equipment e.g. premium seats, to name just a few. Should the currently available model not suit your requirements, please contact us to better understand your application requirements and let us propose you an electric motor design.
