An AC motor is an electric motor that uses alternating current (AC) to turn electrical energy into mechanical motion. You’ll find these motors in a variety of places, from industrial machines to household appliances and HVAC systems, all because they’re efficient and built to last. AC motors mainly come in two types: synchronous and induction, each tailored for different tasks. They’re known for their smooth operation and low maintenance, making them great for both continuous and variable-speed uses.
