Specifically designed to be driven by two inverters, the AF440 ensures unparalleled performance in demanding powertrain scenarios.

Understanding Axial Flux Motors

Axial flux motors represent a distinctive type of electric motor where the magnetic flux flows parallel to the axis of rotation. This innovative design, featuring a short axial length, ensures a more compact structure and enhanced power density. Known for their efficiency, reduced cogging, and quiet operation, axial flux motors are ideal for diverse applications, including electric vehicles, robotics, renewable energy systems, and high-torque scenarios.
