What is input of BLDC motor?
“As its name sugests, the input is DC, you supply DC voltage to BLDC motor, which is then, using transistors, converted to something like AC. So, a BLDC motor is pretty similar to a permanent magnet synchronous motor. It has a permanent magnet for a rotor, and a three-phase stator winding. Difference is that with a synchronous motor you supply AC to stator windings, and with BLDC you supply DC which is converted to AC using electronic switches (transistors).“
