🐹 Can You Run A 380V Motor On 480V

^{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 380V motor run on 400V supply?} Can you use 400V 50Hz on 480V 60Hz power source? 400v 50Hz equipment on 480v 60Hz power system An induction motor at 0.75 kW (approx. 1 HP), 50 Hz, 400v AC, set the motor Hz in the VFD to 60, then the Motor Voltage to 480v AC. This will increase the motor output to approx. How much voltage do I need for a 50 Hz motor? 5. It is actually quite simple. It the nameplate states Δ/Y 220/380 this means that this motor is designed and can be connected in delta, if the line voltage is 220 volts. If the line voltage is 380 V then the motor can be connected in star. This comes from the fact, that the the max allowed voltage per motor winding is 220 volts. 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? ^{That way a motor can be designed to run at either of two voltages, 240 V, delta or 415 V, star for example. If you connect the motor delta and connect it to 415 V, that is too much voltage for the design. The motor will draw excessive current and overheat.} If it's an old motor I would probably run it as long as it will last at 480V and then have it rewound (480V) or purchase a 480V motor. If you know who owned it before you could call and ask if they ran it at 480V. 08iC.
