All the starters you have mentioned is for starting and
running the motor. DOL starters are usually used for smaller
motors where the starting current will not affect the
distribution system or the motor itself or the connected
machine, wheres star delta starters are used for bigger
motors and where the winding terminals are available for
such starting, whereas the two speed starter can be only
used if you have a motor with two speed windings.
If your 20kw motor comes with two speed termination than you
can use the two speed starter if not than you may use
inverters where by selecting the frequency you may vary the
speed of the 20kw motor
