What is the Main Difference Between AC and DC Motor?

In BLDC (Brushless DC) motor, the stator is made of multiple coils that surround the rotor armature made of permanent magnets.The DC is changed into 3 phase AC using thyristors & supplied to the stator coils to generate a rotating magnetic field. In such motors, the input is applied to the stationary part thus it does not require brushes or commutator.
