Unlock new design possibilities with latest-generation smart actuators

Combining AI, sensing, & motion control

The EVLSPIN32G4-ACT brings innovation in motor-control systems

The EVLSPIN32G4-ACT edge-AI motor-drive reference design, based on the STSPIN32G4 intelligent 3-phase motor driver, is making it easier to build smart actuators. The board connects directly with ST's wireless industrial sensor node, STWIN.box (STEVAL-STWINBX1), to accelerate the development of systems that combine motor control, real-time analysis of environmental data, and IoT connectivity.

By combining cutting-edge motor-control systems with data science, the EVLSPIN32G4-ACT achieves breakthrough performance and ensures sustainable profitability. The STWIN.box contains high-quality sensors that capture information about the status of actuation engines, while high-speed data-logging capabilities facilitate the creation of advanced solutions based on edge AI and machine learning. By blending environmental and control data, system engineers gain a clear understanding of how an application is operating, can identify anomalous conditions, and leverage data-driven algorithms to guide troubleshooting and performance optimization.
