World's lightest electric motor at its size

Ultra light and compact

Axial Flux

Flat motor technology for drones and aerial applications

We are developing an ultra light electric motor. We are working on doubling the torque and cutting the weight by half at the same time. This is where the seemless efficiency comes from.


Technical Specifications

Voltage DC 22.2V
Nominal speed 2200rpm
Nominal Torque 1.55Nm
Nominal Power 357W
Fundamental frequency 400Hz

This all from ~250gram motor! Up to 50% lighter compared to its equivalents!


16 cores, 256GB RAM, 15 hours calculation time: And the results just as expected!

Find out 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. After about thirty minutes of flight, the majority of drones must land and they remain grounded until the battery is recharged. If you project UAVs to niches like search and rescue operations, aerial filming and photography, 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.
