Resumen de Rotor in Motor.
This article looks at advances in making U.S. industry more energy efficient. The development of the three-phase AC induction motors which can convert as much as 90 percent of the power they draw into rotary mechanical force should help industry save energy when running electric motors that drive pumps, fans, conveyors and other devices. The parts of made of copper which cuts resistive losses in rotors. INSET: On the Road with Copper.
