What is the US calculation of 110V 60hz?
Do you mean definition? If so 110V = 110 volts-60hz = 60 hertz. Hertz is the cycles that the electricity runs at. 60hz. is the US standard. Europe is at 50hz.
How can you determine if an electric motor is 50HZ or 60HZ if there is no name plate?
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
Is there anyway to get 120V 60hz from a 100V 50hz power supply?
A motor-generator or a solid state power converter can do this.Motor-generators are an old electromechanical technology. In this case you would use a 240V 50Hz synchronous motor and a 110V 60Hz generator with their shafts connected so the motor turns the generator.Solid state power converters use a high power rectifier to convert the input AC to DC, a precisely tuned oscillator to set the output frequency, and a high power class AB push-pull amplifier powered by the high voltage DC and driven by the oscillator to generate the output voltage.
Can you use a 480V 60hz deep fryer on a 380v 50hz power supply stepped up to 480v 50hz by a transfomer?
It is an extremely expensive way of utilizing the deep fat fryer. You should look into changing the heating coils in the fryer to utilize the new voltage. That said it can be done.
Can supply 660volt 50Hz by 660volt 60Hz?
It depends on the nature of the load. For example, a resistive load (e.g. heating) should be no problem whatsoever. But if the load involves magnetic circuits (i.e. transformers, motors, etc.), there may be a problem with overheating which could damage any insulation.
