Here we are showing a tutorial on how to control the speed of a permanent magnet synchronous motor ( PMSM ) which are also known as AC brushless motors using SOLO and Arduino as the commanding unit. The control is done by SOLO in sensorless Closed loop mode with a simple tuning for speed controller gains. to know more pls visit our website: https://solomotorcontrollers.com/control-speed-pmsm-arduino-closed-loop-sensorless-mode/
