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 do you change the connection of single line to 3 phase line of DC motor?
There is no such thing as 3 phase to a DC motor. DC is direct current and is totally different from AC. 3 phase only exists in AC or Alternating Current
Why neutral cross section is half the phase in three phase cable while it has to carry current of summation of all phase..?
The current carried by the neutral of a three phase four wire system is the un balanced current. If the three phase system was completely balanced on all three phases there would be no need for a neutral, eg a three phase motor. This neutral current will be less that the phase current so a reduction in the neutral size is allowed.
What is locked rotor in three phase induction motor?
A motors locked rotor current is the same as the motors starting current. This is the point where the voltage is applied to a non rotating motor, time cycle zero. Because the motor is not rotation and generating a back EMF to oppose the inrush current, the current will go as high as 6 times the running current of the motor.
What size capacitor is needed to start a 1 hp 14 amp 110V motor?
A single phase motor does not actually require a capacitor. This device is only needed when a split phase motor is utilised. A split phase motor needs a device to regulate the power factor associated with the split phase.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
How many percent will be the starting current for motor?
Motor starting current is typically 5-7 times the rated current of the motor. (For three phase induction motors)
What should be the current of siemens 75 kw motor at no load?
starting current of 3 phase 75 KW induction motor
What would be the horse power required in a 3-phase motor to replace a .5 horsepower single phase motor.?
You still need the same horsepower. The advantage of the three-phase motor is that it will draw lower current.
How do you change the connection of single line to 3 phase line of DC motor?
There is no such thing as 3 phase to a DC motor. DC is direct current and is totally different from AC. 3 phase only exists in AC or Alternating Current
What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 amps.
What s the role of capacitor in a single phase induction motor?
to start the motor and give more current to motor to run
Why is a capacitor NOT used in a single phase motor?
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.
Why one phase shows 0 Amps while a delta connected 3 phase induction motor runs?
Cause 2 phase is applied to the motor and another phase is disconnected ... in this condition ur motor cannot run longer ,it will trip on over current or burn ur motor winding .
Will 3 phase AC motor stay running if you remove 1 phase?
Yes but it will not start. Usually if you lose one phase the current will go higher on the other phases and the motor overload protection will disconnect the motor from the supply voltage.
How do you make correct setting for overload of a 3 phase motor?
125 percent of full current rating of the motor
What is the cable size for 600V 3 phase ac motor?
you need the current of motor or the KW/HP rating
