Answer / rajesh kumar

For induction motars Reduce some number of turn with there
armeture winding and induced flux is poor. thus still motar
runing in to low speed at lower electricity.

Answer / praadeep_dd@yahoo.com

If we want low electricity to lower speed of fan we put a
regulator.(Insert resistance in series.)

Answer / amrinder

Please clarify.......... if we insert resistance in series
then it will consume electricity . Thus stiil electricity
consumption is same.

Answer / chandra

We can reduce the supply voltage using thyristors.So, the
speed and power consumptions both are reduced.
