Yes. It will work OK but run about 20% faster than the name plate indicates.
No 380 volts is too wide a spread to use a 220 volt motor on.
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
No it will fry the motor use a voltege reducer
Use a transformer.
batteries are only used for DC CIRCUTS. if the motor is a DC MOTOR you can.
No, you will need a commercial mixer for that.
No because the pump motor will run too fast and the lifetime of the fridge will be severely reduced.
Most 220 volt equipment will work on 208 volt supply. If the machine has a resistive load then the watts output will be lower than if supplied from a 220 volt source. If it is a motor load you will find that the equipment may run a bit slower but most motors will take the lower voltage. If the machine is a plug in device, install the appropriate receptacle to match the pin configuration and plug it in. If it is a hard wire installation this should be done by a qualified person.
If you mean a dual voltage motor 120/240 then yes these will operate on a 240 volt home distribution system.
If a motor is designed to run on different voltages there will be a wiring diagram on motor plate for 120 volt wiring. If not you will have to use a step up transformer to convert 120 V to the higher voltage.
You cannot run a three phase motor on single phase power. You'll burn the motor up within minutes. By the way, I've never seen or heard of a 380 volt motor. Do you mean a 480 volt motor? If so, the only way you can power it is with the correct full voltage and a 3 phase power supply.
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
