Connect the 3 conductors of the power source to the 3 conductors of the motor turn the motor on for a brief moment to note the direction that it turns if the direction is reversed swap any 2 conductors. Try this: www.tdk.co.jp/tefe02/e9123_zrgt_mf.pdf

How do you start a three phase motor to a single phase power supply?

You don't. A three phase motor will not start unless it is connected to a three phase supply.


How is a three phase agricultural motor used when there is no power supply?

With no three phase power supply you can't use a three phase motor of any kind at all!


How do you wire a three phase motor with two speed to a single phase power supply?

A three phase motor requires a three phase power supply. You can not run a three phase motor on a single phase power supply unless you provide some kind of converter, such as a motor-generator set or an inverter. You might be able to get the motor to rotate on single phase, if you provide starting torque somehow, but you will not get rated power in that configuration.


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 is a static converter?

A static converter allows a single phase supply to operate a three phase motor. Basically it converts the single phase supply into enough energy to power the three phase motor.


How does a three phase motor work on a two phase power supply and how do you wire it up?

A three phase motor will not work on a 2-phase power supply, it needs a 3-phase power supply. Two phase electrical services are no longer the standard for electrical distribution. You would need to get an expensive phase-changer to convert your normal single phase power supply to three phase. Depending on the power output you require from the motor, it can often be much cheaper to buy a suitable single phase motor, new or secondhand, instead of buying a phase-changer as the power supply for a three phase motor. If you really do want use that three phase motor you may find it worthwhile to contact your electricity supplier first, to ask if they can install a three phase service for you to use and what the cost would be. Otherwise, after you have bought the expensive phase-changer unit, you may find out later that your electricity supplier could have upgraded your service to three phase for a lower cost!


Can you connect a 3 phase motor to a 1 phase supply?

No. You need a three phase supply to run a three phase motor. If you only have a one phase supply, you could use an inverter or a motor-generator set, but by the time you did that, it would have been more cost effective to simply get a one phase motor, or (in the bigger case) upgrade to a three phase supply.


What circuit you can use to run three phase motor?

It must be a three phase supply service to run a three phase motor.


What volatge consider three phase power supply?

consider 380-440V for three phase power supply


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 static converter can a power supply of computer is static converter?

A single phase supply can operate a three phase motor with a static converter. No a power supply of computer cannot be fed through the static converter.


What will happen if you interchange the supply legs of a three phase motor?

If you interchange any two of the supply legs of a three phase motor, the motor will operate in a reversed rotation than is did before the interchanging of the supply legs.


Can you run 3 phase motor with 2 phase power supply by using a capacitor?

Two-phase power as strictly defined has not been available for about 100 years. A three-phase supply with one phase disconnected is really only a single-phase supply and using a capacitor to create the third phase would not really work because it cannot accommodate changes in the current drawn by the motor.


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 motor work on single phase and three phase drive?

I expect you are talking about induction motors. The drive is called a VFD, variable frequency drive. As the motor speed is proportional to frequency, it can be controlled within reason by varying the frequency of the supply using a specialised inverter. As the frequency varies, the voltage to the motor is also controlled so that the current remains in the ratings. The maximum torque is more or less constant as it depends on current. The speed changes, so that means the output power varies with the speed, as power is proportional to speed and torque. It is possible to find models that use a single phase motor with three phase supply, or a three phase motor with single phase supply using this method, as the power to drive the motor is regenerated. However it is best to use a three phase motor, and the supply may need to be three phase to provide enough power for larger motors. Note that at low speeds the fan cooling becomes an issue.


Can a three phase motor run on a DC supply?

Yes, a three phase motor can run on a DC supply. You will need to provide an inverter, or a motor-generator set to do so. (In practical terms, the answer is no, because the costs will be high for any kind of significant power.)


Does a transformer play a vital role in connecting a three phase motor to a single phase power supply?

To do this, you will need to phase shift the single phase power supply into three distinct phases that are 120 degrees out of sync with each other. Phase shifting transformers can be used for this, but there might be other ways as well.


How do you convert a three phase power supply into single phase power supply?

Any two legs of a three phase supply are classed as single phase. L1 - L2, L2 - L3 and L3 - L1.


Can a 3 phase electric motor be wired to 1 phase?

Supplying power to a 3-phase motor using a single phase is termed "single phasing", which is, in general, not good for the motor. Depending on the connection, one phase or two phases will have higher than normal current draw, which could damage these legs. If lightly loaded, the motor might be fine. You need to supply three phase power to a three phase motore for it to operate normally and be able to pull it's specified load. If all you have is a single phase, there are power devices made to give you three phase power from single phase.


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.


Why three phase motor are self start motor?

Because a three-phase supply causes a steady rotating field inside a three-phase motor, so the torque is a constant torque in one direction.


Why doesn't a shunt motor operate on a single phase AC supply?

Shunt motors do operate on single phase AC. There are millions, if not billions of them worldwide running right now.Make certain your voltage supply is correct for your motor. Also, make certain you're providing the proper amperage. Make sure it's not a three phase motor. (three phase motors won't operate on single phase power.) If your supply voltage and amp supply is correct and the motor still doesn't run, you've got a bad motor.


What Difference between a single-phase power supply and a 3-phase power supply?

A single phase power supply has two "hot" legs or conductors which have a sine wave that are 180 degrees apart. A three phase power supply has three "hot" conductors which have a sine wave that are 120 degrees apart. You can thank Nicoli Tesla, whose birthday is today for the three phase or polyphase power supply and of course all alternating current!


What is the use of capacitor in three phase induction motor?

The only association of a capacitor with a three phase motor is for the correction of the power factor of the motor.
