STMicroelectronics Servo Drive Solution for Multi-Axial Position Control with Ethernet Real-Time Motor Control for

The STMicroelectronics STEVAL-ETH001V1 servo drive evaluation board has been developed to address three-phase PMSM applications oriented to multi-axial position control and connectivity. The evaluation board embeds a motor control power stage, a digital actuation section and a power management section. The motor control power stage hosts the STDRIVE101 half-bridge gate driver and six STH270N8F7-2 power MOSFETs, featuring real-time connectivity with EtherCAT communication protocol supported by the NETX90 network controller, whereas the digital actuation section hosts an industrial IO management section with CLT03-2Q3 (input) and IPS160H (output).
