You lose one third the service so the motor overheats and runs slow if at all.

Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
What you basically want is will each phase take 26 Amps current for 15HP 3 phase 415VAC motor?
Yes. In a 3-phase motor, all 3 phases have the same current.
How much more efficient is a 2 hp 240 v 3 phase motor compared to a 120 v single phase 2 hp motor?
I would guess it would use a third less than a single phase motor. The voltage differences don't save but 3 phase does. A 3 phase motor also starts easier.
Which phase is the reverse phase?
Connecting Phase A, B and C to the motor leads will make a 3 phase motor run in one direction while interchanging any two will make the motor rotate in the opposite direction.
Why would you use 2 point starters instead of 3 point starters for a motor?
traditionally, 3 contact starters are for a three phase motor and two contact starters are for a single phase motor.
How can you protect 3 phase submerssible motor 1.5kw from being burnt due to low or high current?
No
Can I test wires from a 3 phase motor to see if its configured in low or high voltage?
Using a multimeter, check the continuity of motor winding from phase to phase ( U to V, V to W , W to U ). Each phase to phase must have a continuity if winding is OK. If any particular phase fails the continuity test, your motor is probably burnt.
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
How do you turn a 3 phase motor in to a generator?
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
Can a starter used for 5 hp 3 phase motor be used for 7.5 hp 3 phase motor?
No.
Is a 3 phase motor a Synchronous motor?
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.
How do you convert or rewire a 20HP 3 phase motor to single phase motor?
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.
What are the advantages of three phase motor over the single phase motor?
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 size motor do you need to run a compressor 2 stage 80 gallon tank i have a 3 phase on it and want to change 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.
What 3 phase conction of eletical diagram?
what is 3 phase eletical conction digram of 3 phase motor
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
When changing phase rotation of a 3 phase motor is this done at the switchboard?
The phase rotation of motor should be always done from motor side i.e The motor terminal box.
