A divided phase windings circuit includes divided phase windings, a power switch circuit comprising at least one power switch and direct current (DC) supply circuit at a midpoint of divided motor phase windings, and non-collapsing DC power supply component to prevent power supply from collapsing when at least one switch is on and conducting. The non-collapsing DC power supply component may include one or more tap from motor divided phase windings electrically connected to power supply, a secondary phase coil winding connected to power supply to power the power supply, one or more resistors and one or more Zener diodes between the divided phase windings and power switch circuit, and/or electrical component to create a voltage drop between motor divided phase windings and power switch circuit to prevent power supply from collapsing when at least one power switch in the power switch circuit is on and conducting. |
