Con un convertidor de frecuencia un variador de velocidad, el motor aportar un valor an mayor. En lugar de hacer funcionar el motor a la mxima velocidad todo el tiempo, el variador de velocidad permite el ajuste de la velocidad a las necesidades reales. Esto tambin hace posible controlar el proceso de forma exacta y en algunos casos aumentar incluso la capacidad del proceso funcionando a velocidades superiores a la nominal. En contraste con las aplicaciones de arranque directo DOL , los variadores de velocidad hacen posible un arranque suave.
