Compact, liquid-cooled inverter for advanced motion and energy conversion systems.

The AXS 500 is a high-performance servo drive specifically designed for demanding mobile and industrial applications where space, weight, and environmental robustness are critical. Featuring advanced Silicon Carbide (SiC) technology, the AXS 500 delivers outstanding switching efficiency, enabling compact and lightweight power conversion with reduced thermal load and improved performance at high frequencies.

Its direct liquid cooling system ensures stable operation even under high current loads, making it ideal for integration in propulsion systems, electric traction, and hybrid aviation. With a wide DC bus voltage range (50–800 Vdc), support for encoderless PMSM operation, and a fully programmable onboard PLC, the AXS 500 is not just a power stage-it’s a smart, flexible building block for decentralized automation and high-reliability energy conversion.

Developed by Phase Motion Control, the AXS 500 combines rugged hardware (IP65-rated) with a rich set of interfaces including RS422, CAN/CANOpen, EtherCAT, and the proprietary EtherPMC bus, ensuring seamless integration in both standard and custom architectures.
