An AC 모터 (Alternating Current Motor) is a type of electric motor that runs on alternating current. It converts electrical energy into mechanical energy, allowing it to power various devices and machines. AC motors are widely used in household appliances, industrial equipment, and HVAC systems due to their efficiency and reliability. There are two main types of AC motors: synchronous motors and induction motors. Synchronous motors operate at a constant speed, while induction motors are more common and can vary in speed depending on the load. Both types play a crucial role in modern technology and industry.
