star delta ::This is a starting method that reduces the starting current
and starting torque. The components normally consist of three
contactors, an overload relay and a timer for setting the time in
the star-position (starting position). The motor must be delta
connected during a normal run, in order to be able to use this
starting method
dol :: this is also a starting method but some what dangerous for heavy motor who can carry heavy load. because this processes fed direct current to the motor.
