cambio rápido y simultáneo de las fases delta-estrella

Significado de las dos expresiones.
Los motores eléctricos trifásicos grandes se arrancan en la combinación de inducidos llamado DELTA. Una vez que alcanza las revoluciones de trabajo se pasa a la distribución de inducidos llamado ESTRELLA.
Ambos cambios deben ser hechos simultáneamente y en forma rápida.
A bajas revoluciones la distribución "estrella" no tiene la suficiente fuerza como para hacer girar el rotor y el consumo de corriente es elevado.
