Answer Posted / baikunth
generally there are two types of speed control systems are
available in induction motor. 1. scalar or VVVF and 2.
Vector or position control.In scalar control method we use
normal drives or cyclo-converters to control the voltage and
frequency for speed variation. but in vector mode we take
the feedback of position of the rotor and accordingly we
fire the device.It is the most complex technology and is
used only for precision speed control systems.
