Commercial electric motors do not use

an electromagnet to rotate the armature

effectively large number of turns of conducting wire in the current carrying coil

a permanent magnet to rotate the armature

a soft iron core on which the coil is wound

Using electromagnet, the magnetic field strength further increase by increasing the current. Hence it will enhance the power of electric.
