The three phase motor is widely used in industry because of it's low maintenance characteristics. Due to the nature of three phase power, creating a rotating magnetic field in the stator of this motor is simple and straight forward. The strength of the magnetic field changes, as the current flow in the coils of wire around the stator poles change.

Where: V L is the line-to-line voltage, and V P is the phase-to-neutral voltage.A transformer can not act as a phase changing device and change single-phase into three-phase or three-phase into single phase.The third difference we want to mention here is that the

lower current than that shown in the table; while motors of lower speed usually take higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual f.l.c from the motor rating plate

To calculate the full load current of a single phase or 3-phase AC motor is pretty straight forward. However, the terms input power and shaft power of the 

3. Conductors with compact and compressed stranding have about 9 percent and 3 percent, respectively, smaller bare conductor diameters than those shown. See Table 5A for actual compact cable dimensions. 4. The IACS conductivities used: bare copper = 100%, aluminum = 61%. 5. Class B stranding is listed as well as solid for some sizes.

The winding with seriously aged insulation should be exchanged. 4. The induction motor sound is abnormal. In two-phase operation, there is a buzz sound. Restart the motor after shutting down. If the motor doesn’t rotate in two-phase operation, find the reason for phase loss and eliminate it. The three-phase current is unbalanced.
