What else can I help you with?
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
What is the minimum voltage a 115vac 400hz 3 phase motor will run?
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.
Can a three phase motor work on single phase power with out burning up?
A three phase motor will not operate on single phase. The motor will run on two phases but will not start. Motors running on just two phases is called single phasing. The line current of the two legs will go high and it is this factor that the motor controller uses to trip the contactor to open the circuit and isolate the motor from the power source.
Why can a run capacitor with a single phase motor remain in circuit after the motor starts?
A run capacitor is used to improve the efficiency and power factor of a single-phase motor by providing a phase shift to the auxiliary winding. Once the motor is running, the capacitor helps maintain a steady motor speed and performance. It remains in the circuit to assist in the motor's operation.
Why three phase motor run in reverse even if it is not wired to run in reverse direction?
If a three phase motor in running in reverse, then one of the phases is reversed, plain and simple. If the wiring is correct at the motor, perhaps the phase reversal occurred someplace else.
What a some of the application of the three phase supply?
use to run motor
Can a three phase circuit be installed in the same conduit or in different conduits?
The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)
Is three phase induction motor continue running when any of the two phase is disconnected?
This question doesn't really make any sense - any of the two phase? A three phase induction motor requires 3 phases to start - if a single phase is lost while the motor is already running then yes the motor will continue to run. A three phase motor will not start if it is missing a phase.
How do you convert 200 volt 3 phase without a common lead to power a single phase 200 volt ac motor with separate phase two speed connectors they are marked Run Start and Common?
Any two phases of the three phase can be used.Connect one phase to the Common and the other to both the Run and the Start.The Common means that it has a common connection with the Run winding and the Start winding. When the circuit is energized both the Run and the Start windings will be energized to start the motor turning (motor needs the extra torque provided by the Start winding to get the motor spinning). Once the motor reaches 75% of normal operating speed the centrifugal switch that is in series with the Start winding will open, removing power from that part of the circuit and the Run winding will keep the motor spinning.
Why to knw phase sequence?
If you reinstall a three-phase motor with two of the supply conductors interchanged, then the resulting negative phase sequence will cause the motor to run in reverse.
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
What do a run capacitor do in a cIrcuit?
A run capacitor in a circuit helps improve the efficiency of an electric motor by providing a phase shift in the electrical current, which enhances the motor's torque and performance. It allows the motor to maintain a steady operation during its running phase, reducing energy consumption and minimizing overheating. This capacitor typically remains in the circuit while the motor is operating, unlike a start capacitor, which is only engaged during startup.
