Motors are the machines which convert electrical energy into the mechanical energy. In this post, you’ll learn the difference between DC and AC Motors.
|DC Motors||AC Motors|
|As obvious from the name, a dc motor uses direct current as input.||An ac motor takes alternating current at its input.|
|The speed of dc motors is controlled by controlling the current in the armature.||Speed is varied by changing the supply frequency.|
|Its construction involves brushes and commutator which require a lot of maintenance.||Their construction is difficult but don’t suffer from wear and tear and are long lasting machines.|
|Are not popular in industries.||Are popular machines in industries almost cover 90% of the electrical industry.|
