These low-cost single-phase motors are 3-phase high efficiency induction motors with the SEMIHEX/sup TM/ connection of the windings to 2 run capacitors. The single-phase winding currents at full load are the same as if the motors were connected to a 3-phase source. The single-phase full-load efficiencies are the same as the 3-phase efficiencies. The line starting current is unity power factor and is approximately two times the full-load current for motors between 10 HP and 100 HP.
