Scalable in diameter
The innovative electric motor design allows scaling up to provide more torque at higher efficiency. The motor can be adapted quickly for your needs based on its parametric design.

Stackable as the power need
The stackable feature which allows a number of motors to be stacked together in a series. With each stack, you will quickly add up power and torque to the electric motor.

Our Electric Motor Technology
Technological progress is defined by many aspects and in many cases you will find product improvements defined by being smaller, lighter and more powerful. These are the exact characteristics that Turncircles is focusing on for advancing electric motor technology.
The Turncircles team is dedicated to developing an electric motor that has superior Power-to-Weight performance compared to its leading competitors. Companies in the Aviation and Space industry can integrate our technology into their electric motor propelled products to reduce weight and increase power. These features can translate into improving flight times for UAV/Pseudo-Satellite manufacturers operating on earth or for reducing costs to launch motor-operated electronic devices into space by saving weight.
Electric Motor Technical Specifications
Turncircles motor design differentiates itself from other motor manufacturers by not using standard windings and any iron for the stators but rather using alternative concepts for providing the magnetic flux for producing motion.
Our electric motors offer a confident balance, backed by impressive specifications. With a nominal speed capacity of up to 6.000 RPM and a robust nominal torque of up to 100 Nm, they are well-suited for various tasks. Operating smoothly within a voltage range of up to 370 VDC, these motors adapt to different power sources.
They can withstand extreme temperatures, from -40°C to +40°C, ensuring reliable performance in various environments. With IP classifications reaching up to IP67, these electric motors stand strong against dust, moisture, and challenging conditions. Their efficiency reaches up to 96%, indicating an energy-conscious design. And when it comes to lifespan, these motors are built for the long haul, with a durable 20-year life expectancy.
Count on our electric motors for dependable, high-performance solutions that excel in every aspect.
Here's a quick summary of our key specifications:
- Nominal speed up to 6000RPM
- Nominal Torque up to 24Nm per stack
- Voltage up to 370VDC
- Temperature from -40C to +40C
- IP Classification up to IP67
