AC vs DC Motor
AC motors use Alternating Current as their power source whereas DC motors use Direct Current for the same. However, both have a wide range of applications and uses in machines but are different from each other at the same time.
Difference Between AC and DC Motors
The key differences between them are as follows:

AC Motor
AC Motors convert electrical energy into mechanical motion, featuring a stator, and rotor, and it have versatile applications due to their simplicity, reliability, and efficiency. AC motor has a wide range of applications ranging from a small electric device used in our homes to the huge machines used in major factories and industries.
This article explains AC motors, their construction, working principles, classifications (synchronous and induction motors), applications, advantages, and a brief AC vs. DC motor comparison.
