AC Motors are electric motors that run on alternating current (AC), which means the direction of the electric current changes periodically. They are widely used in various applications, from household appliances to industrial machinery, due to their efficiency and reliability. These motors typically come in two main types: synchronous and induction. Synchronous motors operate at a constant speed, while induction motors are more common and can vary in speed depending on the load. Both types are essential for converting electrical energy into mechanical energy, making them crucial in modern technology.
