I bought a 3ph 480v I-R compressor that uses a PAIR of 1ph isolation transformers as a power conditioner. So the PC is actually setup 480v in/ 480v out. I only have 240v, 3ph power. The isolation transformers can be connected as 240v primary. With what I have, is it possible to setup the PC 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. But if you are in the US, don't use 400V, it will be very difficult to find equipment for it. Yes, 480V gear will work, but you might as well then use 480V everything. But transformers and motors are not going to be as readily available in 400V versions. If you are not in the US or Canada, I would check into what everyone around you uses. Can a 380 volt motor run on 480? Can you run a 380V motor on 480V? 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.

(4) Manual Self-Protected (Type E) Combination Motor Controller, UL listed for 208 Wye or Delta, 240 Wye or Delta, 480Y/277 or 600Y/347. Not UL listed for use on 480V or 600V Delta/Delta, corner ground, or high-resistance ground systems. (5) When using a Manual Self-Protected (Type E) Combination Motor Controller, the drive must be If the voltage and current to the motor are 400 V and 8.6 A, respectively, determine the power factor of the delta system. To conduct the correct three-phase power calculation to the problem given above: Identify the given parameters — active power = 5 kW, phase voltage = 400 V and line current = 8.6 A. Choose the connection type. You can use it, but there are two ways to use it 1. When the motor operating frequency is less than: 50 380/480 = 39.6hz, the motor can meet the constant torque operation. At this time, even though the power supply is low, the constant flux of the motor can be maintained by changing the frequency year on year, so the maximum torque is not lost 2. Would like to run a five hp 230 volt three phase motor (having 6 leads) on a 480 volt three phase bus via a VFD. Have Delta and AB drives available. Did a quick test of this idea today using one of the 480v Delta drives with these settings: 480 volts and 120 hz . figuring the motor operating at 60 hz, given rudimentary linearity of the v/f Hjad2Ow.

can you run a 380v motor on 480v
