It depends on how, and with what you change them.
You will need to install a phase converter or change the motor to single phase. You can find a licensed electrician at www.contraxtor.com
no
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.
nothing
yes . A change of motor would be required. The motor windings would have to be totally different. three hot leads instead of two. And three phase would have to come from your provider.
When energy is added during a phase change the energy is used to break molecular bonds.
This is a change of phase from liquid to solid.
Is the motor 3 phase? Thats what im guessing. You would get an unbalanced load across the windings of the motor, the other 2 phase's would try to compensate and ruin the windings. 3 phase motors are obviously supposed to have 3 phase input. Weather it be in star or delta. I wouldnt try and run it if i were you!
You probably need a 5hp or 7hp motor. Look for HP rating o the 3 phase motor and select the same for single phase. 3 phase has same power but is more efficient at electricity use. Also consider a 3 phase converter. It allows a 3 phase motor to run on single phase service.
yes
Reverse any two line leads connected to the motor will reverse the directional rotation of the motor
DC motor: Switch your leads. AC single phase motor: Direction cannot be changed. The motor will run the same direction regardless of how your leads are terminated. AC 3 phase motor: Switch any two leads.
