AC motors, or alternating current motors, are electrical devices that convert electrical energy into mechanical energy using alternating current. They are widely used in various applications, from household appliances like fans and washing machines to industrial machines. AC motors are popular because they are efficient, reliable, and require less maintenance compared to other types of motors. There are two main types of AC motors: synchronous and induction motors. Synchronous motors run at a constant speed, while induction motors can vary their speed based on the load. Both types play a crucial role in powering our everyday devices and supporting industrial processes, making them essential in modern life.
