Use only one of the legs (L1-L3), and the neutral. Some three phase circuits don't have a neutral. If that is the case, then you cannot run single phase.
CommentYou don't need a neutral, providing the voltage is appropriate, you can get a single-phase supply by connecting the load between any two lines.
There are three ways to do this typically. (besides replacing the motor).
There are static converters which have no moving parts but you lose some power and starting torque.
There are rotary converters which require a single phase motor to turn a three phase motor which acts as a generator to drive the three phase motor of the device you want to power. This of course ends up with three motors including the one you have to begin with, but it works well.
THe third and best solution is an electronic three phase source. It works off your single phase and generates DC. The DC then powers a special three phase inverter synthesizing three AC waveforms 120 degrees out of phase which powers your motor. The best ones allow changing the frequency which will make it a variable speed controller and also allow reversing the phase rotation to run the motor bidirectionally. These are fairly compact and can be quite versatile and not terribly expensive - that would be my first choice.
No, because the three phase drive is always monitoring the three phase output for line loss. If one phase is missing the drive will shut down with a phase loss alarm.
With a synchronous motor shorting the slip-rings together should make it work as an induction motor although perhaps not to an optimal degree.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
The parts of a motor includes the valves,piston rings,piston and the cylinder just but to mention a few. It uses the power of the magnetic fields to convert electricity into motion.
take two dc motors..................... connect the spindle of 1 motor to a hollow pipe so that the pipe should also rotate when the motor is given dc current (one can take an empty pen refill for that).... now fix the spindle of another motor to the other end of the hollow pipe...... the two terminals of the 2nd motor is now the terminals of the dynamo which will generate dc current........
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
A motor convert electrical energy to mechanical energy.
You cannot convert a turbo diesel driven car to a petrol motor. You have to buy a car that uses the petrol motor.
short the rotor terminals.
Into units of what?
No.

are you tring to convert a car from coil packs to a distributored motor

You need to make a generator
An electric motor.
The easiest way would be to convert the AC power to DC by using a rectifier diode and a filter capacitor. In that way you can now run your DC motor on DC.
