With components for VFD outputs from 1.5 to 400 kW and line voltages from 220V, 230V, 240V ( single phase ), 380V, 400V 415V (three phase), the variable frequency drive feature decisive characteristics such as: individual travel, lifting, turning and slewing motions by infinitely variable speed control independent of the given load; Motors for use in the US are designed around our utility voltage of 480V 60Hz, so 460/60=7.6V/Hz. Your motor is designed around 380V 50Hz, and 380/50=7.6V/Hz! As countryman said, you motor will run faster no matter what, but you don’t necessarily need to buy a transformer. Can a 380 volt motor be run at higher voltage? A motor provides torque based on a direct relationship to the ratio of voltage and frequency it was designed for, typically +-10%. So a motor designed for 380V 50Hz is a ratio of 7.6:1, a motor designed for 460V 60hz is also a ratio of 7.67:1, so virtually identical. JRaef. That will depend on the motor. The DC bus is the line voltage x 1.41, so on a 575V supply, the DC bus is going to be 810VDC. That means all of the PWM pulses will be 810VDC no matter what you program the RMS voltage output to be. That will be hard on a 480V wound motor, and even worse if there is any distance between the drive and motor Ususally the motors can run with 10 % voltage variation, if the motor is 380 V-60 Hz could work proper at 418 Volts-60 Hz, if the motor is feeded with 460 V this will be experiment an over voltage condition, so you most check the load if the motor is not loaded 100 % I think you can do it in 80% load condition. Basics. Frequency Converter, also named as AC power source, is a electronic device to convert fixed frequency (50 hertz, 60 hertz), fixed voltage (110V, 120V, 208V, 220V, 230V, 240V, 380V, 400V, 440V, 480V etc) to variable frequency (50Hz/60Hz or 400 Hz adjustable) and variable voltage (adjustable) with pure sine wave output to compatible with Picture 1 shows the data plate of a 370Watts PFAFF clutch motor which can be run on 220V and 380V. Picture 2 shows the original 380V setup of this motor. Picture 3 shows the setup of the same type motor changed to a 220V + capacitor for clockwise rotation direction. Please compare the pictures with the diagram in post 1. 208V Single Phase and 208V 3 Phase power are easy to use, but hard to understand. If you want a simple understanding but aren’t electrically minded, start with a simple analogy you can build on. I like the bicycle analogy. Bicycle Analogy . A tandem bicycle has two people providing power with four legs (pedals). .

can you run a 380v motor on 480v
