Our technologies are designed to deliver the highest safety and performance, and optimum platform integration.

Torque density plays a big role in performance. This is the torque you're driving out of the motor divided by its total weight, including all its auxiliary systems. By using air-cooling in our design rather than liquid cooling, we can reduce overall system weight and increase torque density, enabling the highest efficiency for the six to eight propeller aircraft we expectto see in the UAM space. We have also chosen a transversal flux motor topology, which in combination with the air-cooled approach maximises the achievable torque.

The torque requirements for our motor design are guided by the UAM market's need to operate at minimum aircraft noise, as they will be operating in cities that are densely populated. Our motor design therefore allows for slower propeller rotations and reduced noise levels.

We are also building on our experience and knowledge of the operating environment and ability to design for it, meeting the requirements operators will need as the industry develops.
