Axial flux light weight custom electric motor

Scalable in size and stackable as the power need

Customize electric motor according to your needs

We offer any size brushless permanent magnet pancake DC motors that can be rapidly tailored to meet your exact specification between 65mm to 425mm in diameter ranging from 56Watts up to 56kW.
Where the size in diameter is reached, our electric motor can be stacked to meet the power requirement. With each stack, you will add up power and torque to the electric motor.

Simply follow below steps

  1. Provide required electric motor power output
  2. Adjust electric motor size if needed
  3. Enter your contact data and notes
  4. Send us the specifications
