will a 220v motor run on 208v

A 10kW 50Hz motor will be a 12kW motor on 60Hz power source. Another concern is the motor appears to be for a 50Hz three phase power supply, but the power supply on site could be at 60Hz 208v, so we must take that into consideration, too. You cant expect the efficiency to remain the same because the 240V device has fewer volts to work with. All our single-phase 220V motors will operate on either a 208V or 240V nominal power supply, which are the most common types available in North America after you move up in voltage size from 110V (or 120V). There is an existing electrical panel box in the laundry room. The 5.1 A rating will be the maximum current that the motor will carry without overheating and will correspond to 208 Volts. That's why motors larger than 2HP are wired only for Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. This isn't a DIY site, but I,will say that the voltage will likely work fine but the higher frequency will cause motors to run faster by 1/5. Yes, it will be fine.
