DIVIDED PHASE SYNCHRONOUS MOTOR CONTROLLER

摘要

A circuit for a motor includes two phase windings forming one half of motor phase windings and two other phase windings forming another half of the motor phase windings. A DC power supply is located at a midpoint of the motor phase windings to receive AC power transferred from the phase windings and convert it to DC power. A first stage power switch circuit comprises a power switch outside of the DC power supply and is electrically connected at a midpoint between phase windings on each half of the circuit. A second stage power switch circuit comprises one other power switch and is electrically connected at the midpoint of the divided phase windings to receive AC power from the motor divided phase windings. A non-collapsing DC power supply component prevents the DC power supply from collapsing when either one of the power switches is on and conducting.
