The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.
That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.
Power stations in USA, Canada and other countries generate ac at 60 Hz.
Power stations in countries in Europe and other world areas generate ac at 50 Hz.
"Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
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.
The higher the voltage, the less amperage is required and is easier to supply power to the device. Motors take much more power than lighting, therefore voltages may be higher for easier transmission.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Check for a blown fuse in one of the phase legs.
This bulb is very likely to be burn out since the 440 supply voltage is very higher than it's rated voltage.

resistance = volt / current . 440 volt across a parallel circuit means the same 440 volt across both resistance s. hence resistance r = volt / current . 440 / 20 amp = 27.5 ohms total resistance
No. The capacitor will short out and possibly explode. On the other hand, the 440 Volt Cap can be used in a 220 Volt circuit.
The appliance should be marked with the correct voltage range, and the voltage applied must lie within this range. Otherwise it might be dangerous.
440 cycles per second. 1 Hz = 1 cycle per second

Grounding monitor
either one could. it depends witch one you unscrew first.

common phase
Depends on the electrical use in the factory. If there's lots of heavy duty machines, then they probably also have 220 v. And some draw higher, 3 phase, or 440, or more.
You can't get 230 from a 440 panel. You'll need a step down trandormer
