usually they say its possible 2 convert a 2phase supply to 3 phase.if its so then how?
As with any motor the function is to turn electrical energy into mechanical energy.
Just use any two of the three terminals that are available, this will give you a single phase capacitor.
zma da ghan mata sa razeEven if I do not understand the language used above I still believe that the answe above is very irrelevant, to say the least.Answer:1. Resistance start single phase motor2. Capacitor start single phase motor3. Capacitor start and run single phase motor4. Capacitor start capacitor run single phase motor
Because from the capacitor characteristics at first it will charge and then it will stsrt to run so when the motor get power from single phase capacitor take time for charging. Amit.
Because they are Ganged ( Grouped ) together , such that they can be tuned through a single tuner.
An ideal capacitor is characterized by a single constant value for its capacitance.

capacitor start motor
A circuit that doesn't require a lot of filtering such as a charging circuit for a battery. In a single capacitor filter, the sine wave or AC doesn't get completely eliminated.
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
Very often a capacitor IS used in a single-phase motor. It provides a phase-shifted current to the starting winding to ensure that the motor runs in the right direction, e.g. clockwise if that is the requirement.
mainly due to undervoltage.
