AC motor definition
"AC motor" is a machine for converting mechanical energy and AC power. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have no commutator (see commutation of DC motors), so they are simple in structure, easy to manufacture, and relatively robust. They are easy to make motors with high speed, high voltage, high current and large capacity. AC motor power covers a wide range, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 1980s, the largest steam turbine generator reached 1.5 million kilowatts. The AC motor was invented by the American Serbian scientist Nikola Tesla.
