How do you wire a three phase motor with two speed to a three phase power supply lead numbers not specified?

There are many types of winding on a two speed three phase motor. The number of wires from the motor should have been stated. This is a guess that the motor is a six lead. The diagram is for a six lead out two speed, one winding, single voltage constant horsepower motor.

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.
Disadvantages of 3 phase induction motor?
One of the disadvantages of the 3 phase induction motor is that it requires a three wire supply. The other disadvantage is that the 3 phase induction motors have poor starting torque and high have in the rush currents.
What is phase fail protection?
In a 3 phase power system, say for a 3 phase motor - it is necessary to have all three phases intact to be able to run the motor efficiently, safely. If any one phase fails , the motor still continues to run but the temperature raises rapidly, due to high current. The motor winding can burn out, can trip off due to overload. Hence a device called phase failure relay is connected. It constantly reads all the 3 phases and cuts off the main supply in case any one phase fails.
How can you include phase failure relay in your star delta motor starter circuit?
The star delta motor starter circuit has to have a control voltage to energize the motor magnetic contractors. A phase failure relay monitors all three phases of the incoming supply lines. The phase failure relay also has auxiliary contacts on it. There are usually two sets of "C" form contacts. The control voltage for the starter circuit must be connected across the normally open (N.O.) contacts of one of these two sets. When the phase monitor is energized these N.O. contacts close supplying the control voltage to the circuitry of the star delta starters. If there is a phase interruption, phase reversal or phase loss, the phase failure relay will de-energize and the N.O. contacts will go back to their de-energized state. If the star delta motor starter is in use at the time, its control circuitry voltage will be lost and the delta motor magnetic contactor will open. The opening of this contactor will disconnect the motor from the failed three phase supply.
How do you find out 3 phase motor watts?
It should me stamped on the information plate. If this is not on it, then there will be the running current stamped on the plate. Multiply this by the supply voltage to find the power in watts. Take the horsepower of the motor and multiply it by 746. There are 746 watts in 1 HP. It is also the same for single phase motors.
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.
Is 3 phase motor run on 1 phase supply?
No. That would be a single phase motor.
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!
Will a 3 phase motor work on grounded B phase?
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.
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 circuit you can use to run three phase motor?
It must be a three phase supply service to run a three phase motor.
Will you produce a 3 phase voltage if you rotate a 3 phase motor physically at its specified rpm?
yes
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.
Can you run a three phase motor with single phase generator with help of phase converter?
Terminology gets misapplied but a 3-phase converter produces a 3 phase supply from a single phase supply. The only proviso is that generator, converter and motor are all suitably rated and compatible.
How do you convert or rewire a 20HP 3 phase motor to single phase motor?
The winding design of the motor will not economically allow this to work. You would have to drive a 3 phase generator to supply it.
Which A motor is to be operated from 230 V 50 HZ single phase AC?
All types of motor can be run from a single-phase supply provided the frequency, voltage and power capacity of the supply matches that of the motor and it has been designed to run on single-phase.
Is schrage motor ac?
As the motor is a three phase machine,it must be AC supply
