Can I run 480 volt , 60 HZ motor at a 380 volt , 60 Hz system?
Yes
Yes, that system is what it is designed to operate on.
Yes, a 220 Volt 50 Hz appliance should work on a 240 Volt 50 Hz supply. The appliance would receive slightly more voltage, but typically a small variation like this should be within the appliance's acceptable range. Just ensure that the appliance is rated for the higher voltage to prevent any potential damage.
120 volts 60 hz
Yes. It will work OK but run about 20% faster than the name plate indicates.
If 50 hz is applied instead of 60 Hz, the speed of the motor will reduce by 10 hz equivalent. If you still want to keep the output speed equivalent to 60 Hz, you will have to use suitable gear box or so, to increase the speed to 60 hz equivalent.
Yes, a 440 Volt 50 Hz device can typically operate on a 380 Volt 50 Hz supply, but it may not perform optimally and could be at risk of under-voltage conditions. Devices designed for higher voltages might require a specific voltage to function correctly, and running them at a lower voltage can lead to reduced efficiency or potential damage. It's essential to check the manufacturer's specifications and recommendations to ensure safe operation.
NO
230 volt 50 Hz.
If the power supply is 60 Hz AC, and the Wii says 60 Hz, there is no problem. The built-in transformer provides DC power to the electronics. Do not try to use a Wii designed for a 50 Hz system at a higher voltage.
Yes, that is exactly right for Australia.
