# You asked: Can a 380V motor run on 400v?

Contents

You can use a 380V equipment on a 400V system with confidence. Take note it’s just a little over 5% of the voltage and most motor should be happy with that.

## Can a 380V 3 phase motor be used or ran to a 440V 3 phase supply?

So the simple answer is no. The more complex answer can be a yes if you know the loading, the heat dissipation, and voltage insulation that these are within the capability of the motor.

## Can I connect a 380V 3 phase 50Hz motor to a 440V 3 phase 60Hz supply?

Firstly a 380V 50Hz motor will run quite happily on 440V 60Hz – that’s typically why they have such dual ratings – since the impedance is more or less a linear function of frequency 380×60÷50 = 456V no problem.

## Can a 380 volt motor run on 480?

The drive will accept 380V, no problem. But the output voltage will be limited by that as well, standard VFDs cannot provide an output voltage that is greater than the input voltage. So if your motor is designed for 480V, you will end up with a limited speed or a loss of torque.

## Can I run a 380V motor on 460V?

A three phase 460V motor operating at 60 Hertz has the same V/Hz ratio as a 380V motor operating at 50 Hertz – approximately 7.6V/Hz. … As long as the load torque does not change between the two speeds (60Hz/50Hz), the motor will draw the same current at both speeds, and no harm will come to the motor.

## Can a 230v motor run on 277v?

First answer: NO, YOU CAN”T RUN A 230 or 240 Volt motor on 277 Volts or 480 Volts. But; Most 230 Volt 3 phase motors are dual voltage and will run on either 240 Volts or 480 Volts.

## How many volts is a 3 phase?

What’s the difference between single phase and three phase? Electricity is either connected at 230 or 240 volts (single-phase, which accounts for the majority of domestic situations), or 400 and 415 Volts (three-phase).

## Can a 400V 50Hz motor run on 480V 60Hz?

This means that if you have motor designed for 400V and 50Hz and you want to connect it into power supply with 60Hz, your maximum allowed voltage will be: 400 / 50 = U2 / 60 => U2 = 60 * 400 / 50 = 480V which is higher than 400V. So, as you can see after calculation, you can supply your motor with 480V and 60Hz.

## Can 50Hz motor run on 60Hz?

Electrical machines designed for 50Hz can usually work safely in 60Hz power supply, but not applicable to 60Hz machines to be run in 50Hz power supply.

## Is 440V the same as 480V?

480V is the voltage between phases of a 3-phase “Y” circuit that’s 277V from hot to neutral. In keeping with 110V versus 120V strangeness, motors intended to run on 480V three phase are often labeled as 440V.

## Can you run 400v motor on 480V?

Electrically, the motor will work fine. The ratio of Voltage and Frequency is exactly the same (400/50 = 8.0, 480/60 = 8.0), so the motor will work at 480V 60Hz and provide it’s full rated torque at nameplate FLA without issue.

## Can a 380V motor run on 415V?

380V equipment has a hard life on a 415V system and overheats because of magnetic saturation. 415V motors on a 380V system overheat because of abnormally high slip.

## What countries use 380V?

Three-phase electric power (industrial applications only)

Country Three-phase voltage (volts) Frequency (hertz)
Benin 380 V 50 Hz
Bermuda 208 V 60 Hz
Bhutan 400 V 50 Hz
Bolivia 400 V 50 Hz

## Can 400V motor run on 440v supply?

You should be ok. You’re slightly above the design voltage maximum but the higher frequency will make up for that.

## Can 400V motor run on 415V supply?

400V Motors will operated on 415V.

## Can a 460V motor run on 400V?

They are good motors, and work well, with the V/Hz/RPM ratio maintained. … The motor current at the low-slip range varies with the load on the motor shaft.
