3 Phase Motor Capacitor star-Delta connection

How do you select a capacitor for a 3 phase motor?

Multiply 0.5 times the square of the voltage. Call this result "x.". Continuing the example, you have 0.5 times 11.5 volts times 11.5 volts, or 66.1 square volts for "x". Divide the start-up energy requirement, in joules, of the motor by "x" to arrive at the capacitor size needed in farads.

In a squirrel cage induction motor, the starter is used only to decrease the input voltage to the motor so as to decrease the starting current. It is T.P.D.T switch used to first start the motor with the winding connected in star and then switch for delta connection in running position.
