From the project

FOC driver for a single BLDC motor.

Brushless motor driver for mini gear motors and servos. This driver focuses on fine force control using field oriented control (FOC). The motor can be commanded to move to track position, velocity, and/or force. The driver will maintain the current wave exactly 90 degrees out of phase to the EMF wave for maximum efficieny. Position is tracked via hall sensors, EMF feedback and I2C rotary sensors.
