This paper explores the potential of RISC-V CPUs for aerospace applications, focusing on the specific use case of Brushless Direct Current Motor (BLDC) control. The project aims to contribute to Brazil’s technological sovereignty by reducing reliance on foreign semiconductor technology. An initial implementation of a basic Six-Step algorithm demonstrated the feasibility of RISC-V for motor control. However, the limitations of this approach led to the investigation of more advanced Field- Oriented Control (FOC). While FOC offers superior performance, its implementation presented challenges related to timing constraints, current measurement accuracy, and rotor position feedback. The project successfully identified hardware requirements and constraints associated with BLDC motor control.
