The W80 AXgen motor is designed for optimal compatibility with WEG’s CFW900 series of inverters, allowing for the operation of multiple motors from a single inverter unit. This innovative configuration eliminates the necessity for additional filtering components, lowering overall system costs and enhancing motor efficiency. The W80 AXgen can improve performance reliability over extended cable runs, with effective operation maintained even at lengths of up to 200 meters.

So What Exactly Is An Axial Flux Motor?

Suppose you’ve never heard of an axial flux motor, axial gap motor, or pancake motor. An axial flux motor is an industrial motor where the gap between the rotor and stator aligns with the motor’s axis of rotation. This design contrasts with the conventional radial flux motor by allowing the magnetic flux to run parallel to the motor’s rotor. The design leads to a compact, lightweight structure that performs exceptionally well in high-torque applications, making it suitable for the electric vehicle industry, renewable energy systems, and various industrial contexts.

Due to its flat geometry, the axial flux motor offers several advantages, such as a compact and lightweight design, a high power-to-weight ratio, and effective cooling. This makes it useful in applications where motors need to be lightweight or compact. However, it also has limitations, including lower torque capacity than radial flux motors and challenges in manufacturing.

Applications for axial flux motors span electric vehicles, robotics, wind turbines, electric fans, and marine propulsion systems, showcasing their versatility across multiple sectors.

WEG's W80 AXgen axial flux motor significantly advances energy-efficient technology, emphasizing sustainability while providing robust performance for OEM partners. Its innovative features and wide-ranging applications are essential to meeting contemporary industrial demands and environmental responsibilities.
