Answer / michael

i dont think it is possible,
because i know 1400rpm is
the rated speed or full load speed,
even we vary the frequency still
it will overload because the
2000rpm is higher than the
full load rpm.

Answer / gumnam parinda

u can use variable frequency drive. Yaskava, fugi,franic are the
drive's compney, u can increase or decrease the speed by increse
or decrease the frequency. This is the best method for speed
purpose and also for protection purpose

Answer / simon peter

Use a 3 phase VARIAC transformer bcs v is directly prop to I & if both r increased the speed will increase automatically.....
