by using dc volts across pairs and with an analog meter to check the deflection of the needle to determine if they are in phase
Yes, my dad worked with motors for many years and did this regularly.
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
A synchronous motor can be a type of 3-Phase AC motor, or not.A synchronous motor is defined by the period of the rotor being synchronized with the frequency of the stator windings' current. The stator windings might be 3-Phase or not (2-Phase would work).Also synchronous motors are not the only type of 3-Phase AC motors. An induction motor could also be 3-Phase AC and has a few advantages and disadvantages over a synchronous motor.
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
Yes the minimum voltage of an 115vac 400 Hz 3 phase motor will run. You can run a single phase motor on a three service but you cannot be run on a single phase.
You still need the same horsepower. The advantage of the three-phase motor is that it will draw lower current.
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
Yes, you can, and it won't burn out IF>>> the horsepower rating is the SAME. Pay attention to wiring and motor rotation. Also check the voltage: the motor voltage must be the same as the voltage between two hots of your 3 phase system. You will only use two hots as this is a single phase motor.
No. That would be a single phase motor.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
No.

The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.
A 3-phase motor produces a steady torque that does not pulsate. A 3-phase motor starts turning in the right direction when switched on without the need for a separate starting winding.

what is 3 phase eletical conction digram of 3 phase motor
It is probably a three phase 50 Hz motor.
