2022-04-03 14:15:31 Using Raspberry PI to control a pair of brushless motors (PMSM, BLDC, or Direct Drive)

This DIY tutorial demonstrates how to control a pair of brushless motors using a Raspberry PI computer and @servosila brushless motor controllers. The entire setup is powered by a single battery just like in an autonomous vehicle design. The first motor is an outrunner type, a kind of what you would use for a vehicle propulsion. The bigger motor comes with a quadrature encoder which means it can be used as a powerful servo.
