BrightBlueJim claims: June 18, 2019 at 8:forty eight pm And perhaps this leaves out the very important difference: BLDC motors are definitely AC synchronous motors. All motors want some usually means of producing a phase distinction between the stator plus the rotor, so that there is a torque made.
