Answer Posted / ashhad khan
first of all why do we call it a drive instead of just calling it as a motor . its because ac drive or dc drive is a combination of a controlling circuit and a motor. so that we can control the speed, direction and regenrative power.
and these drives are mostly use in railways thats why sometime they will be called as traction motors.
controlling circuit used is a combination of thyristors and diodes so as to change the voltage or frequency to control the speed of ac drives.

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
