For example,
A motor voltage 3x230V to voltage 3x400V.
Section of wires original / V3(1,73)
Number of windings original x V3 (1,73)
Connections of coils have to stay the same, as well as external connections.
Most motors do have different voltage regarding the external connection.
Most motors < 5,5kW = 3x230V/400V
5,5kW and higher : 3x400V/690V
The difference between the voltage is in this case made by external connection (Delta/star)
Delta : L1 = U1-W2, L2 = V1-U2, L3 = W1-V2
Star : L1 = U1, L2 = V1, L3 = W1 and connection between U2-V2-W2

How do you tell how you have a dual voltage motor?
The motor has the ability to operate on two different voltages and still maintain the motor characteristics of the nameplate specifications. As the voltage goes down the amperage will go up in value but the HP and RPM will remain the same.
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.
Will 220 volt work in a high volt 3 phase motor?
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
Which one of the following statements is true of a split phase motor when it is starting the speed is high the torque is high the current is low the voltage is low?
The first statement is true, the motor needs a power source to operate.
How many volts in a dc motor?
A DC motor can be built to operate on any voltage.
How do you tell how you have a dual voltage motor?
The motor has the ability to operate on two different voltages and still maintain the motor characteristics of the nameplate specifications. As the voltage goes down the amperage will go up in value but the HP and RPM will remain the same.
What is need to operate an electric motor?
Voltage is needed for both AC and DC motors.
Can an air conditioner unit running on 250 volts be run directly by 120 volts?
No, the unit has to operate on the voltage specified. The internal controls are all designed to operate on a 240 volt input. The motor in the air conditioner will not operate at the lower voltage and without this compressor motor operating the unit will not get cold.
Is special switching needed to switch 1HP pool motor?
If you are talking about turning on and off the 1 HP pump you will need to know what voltage the motor is and buy the correct size switch to operate at that voltage.
Will it hurt a 4.8 volt dc electric motor if you put greater then 4.8 volts on it?
Yes. DC motors require the specified supply voltage to operate correctly. Supplying a higher voltage to it will burn up the motor.
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 is difference between nominal and terminal voltage?
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufacturer designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
Will 220 volt work in a high volt 3 phase motor?
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
How do you determine a 3 phase motor and each winding?
To see if the motor is three phase or single phase look at the motor's nameplate. There it will tell you what the voltage needs to be and what system phase the motor needs to be connected to operate properly.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
Which one of the following statements is true of a split phase motor when it is starting the speed is high the torque is high the current is low the voltage is low?
The first statement is true, the motor needs a power source to operate.
