What amp would a 440 3 phase motor have?
Need to know the horsepower of the 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.
Do you need starter for 0.5HP three phase induction motor?
You never need a starter for a three-phase motor.
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.
You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
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.
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.
Why capacitors are not used in three phase motor?
There is no need. The three-phase supply provides a rotating field in the motor, rotating in the right direction, so there is no need for a starting capacitor.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
How do you convert a single phase to a three phase motor?
You need three phase power to get three phase power. If you only have one phase, you will need some kind of inverter or motor-generator set. Generally, however, the demands of a three phase motor will exceed the capability and efficiency of these "tricky" solutions. It is best to simply contact your local power company and have them provide the proper three phase power to your facility.
Would 10mm sq cable suit an 18kw 3 phase 415 volt motor 25mt length?
The motor would draw about 24 kVA which is 35 amps. For this you would need 10 mm2 cable.
Would 10mm sq cable suit an 18kw 3 phase 415 volt motor over 25mt length?
The motor would draw about 24 kVA which is 35 amps. For this you would need 10 mm2 cable.
