Large low-cost single-phase SEMIHEX/sup TM/ motors

These low-cost single-phase motors are high efficiency 3-phase motors with the SEMIHEX/sup TM/ connection of the windings to two 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.
