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.
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.
You have one hp three phase motor where as available power supply is only single phase how can you run this motor?
I assume that by two-phase, you really are talking about a supply with two hot wires and a neutral, such as 120/240 volt. This is single phase power, it just has power taps on both ends of the transformer winding, the neutral is the center tap. I don't think it is possible to convert or rewire your motor. A large 3 phase motor must be run on a 3 phase electrical supply. It will not…
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…
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 is the simplest way to run a 3 phase 380 V motor of about 1 KW directly on 220 V single phase supply without resorting to rewinding or frequency converters?
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.
Does a transformer play a vital role in connecting a three phase motor to a single phase power supply?
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…
