SimpleFOC is an Arduino library that implements Field Oriented Control algorithms for BLDC and stepper motors across multiple hardware platforms.
The library addresses the challenge of controlling brushless DC motors and stepper motors, which offer superior dynamics and power compared to regular DC motors but require complex driving algorithms. Field Oriented Control is one of the most efficient control methods for these motors, yet existing solutions are typically tied to specific hardware configurations and microcontroller architectures. SimpleFOC provides a unified, hardware-agnostic implementation that abstracts away this complexity, allowing developers to write FOC control code once and deploy it across different combinations of motors, sensors, drivers, and microcontrollers without rewriting the core algorithm.
The library is designed for hobbyists and makers entering the BLDC motor space who need a low-cost, accessible solution without deep expertise in motor control theory. It suits projects requiring smooth, efficient motor control where standard PWM-based approaches are insufficient. The tool is particularly valuable for those planning to experiment with different hardware combinations, as it eliminates the friction of relearning or rewriting control logic when switching between motor types, sensor configurations, or development boards. SimpleFOC also extends FOC benefits to stepper motors, an area where such solutions are rarely available.
Development activity shows consistent engagement with regular commits to the main development branch and ongoing release cycles. The project maintains comprehensive documentation and actively supports a community ecosystem of third-party driver boards built around the library. The codebase demonstrates sustained refinement and expansion of hardware support across multiple microcontroller architectures and peripheral configurations.
