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 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 a 440V motor run on 380V?
Can a 460V motor run on 380V? … 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 you use a 380V motor on 415V?
If they are made to operate at a wider range of voltage, then yes …… 380 volt is also can be used.
What happens if I run a 50Hz motor at 60Hz?
It will run with following problems for a 50Hz motor running on 60Hz: The core loss will increase and cause over heating of core. As the core loss will increase, the Power Factor of motor will reduce. The motor speed will be higher, so shaft load will increase.
Can I run a 50 Hz motor at 60 Hz?
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.
What is the difference between 415V and 440V?
415V is the RMS value between line to line and 440V is the maximum peak value.
Can 440V motor run on 415V supply?
The 440V-60Hz equipment has to run on the 415-60 mains. That way they skip the light-transformers as phase-voltage@415V = 240V.
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.
Is 380V the same as 400V?
It’s a bit more complex in Europe where there are still legacy systems running at 380V and 415V, but both are now nominally 400V. 380V equipment has a hard life on a 415V system and overheats because of magnetic saturation.
How many volts is a 3 phase line?
3 phase system is expressed with line voltages. The line votage is 440 volt. Also the voltage between any one phase and neutral for a 3 phase system is 240 volts.
How do you get 415V from 3 phase?
The three phase lines and the neutral together give a 3-phase 4-wire supply with a RMS voltage of 240√3 = 415V.
