Due to the huge development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have no commutators (see DC motor commutation), so the structure is simple, easy to manufacture, relatively firm, and easy to make into high speed, high voltage, large current, and large capacity motor. The range of AC motor power is very large, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 1980s, the largest turbine generators had reached 1.5 gigawatts. The AC motor was invented by Nikola Tesla, a serbian-American scientist. |
