ABSTRACT:
A brushless direct current motor includes a permanent magnet rotor and a set of stator windings. The motor further includes a circuit for changeably connecting the set of stator windings to operate in a first electrical configuration or a second electrical configuration. In the second electrical configuration, the circuit connects only some of the stator windings for receiving current. The circuit electrically isolates the unused stator windings from the used or connected stator windings.
