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.....

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
