Abstract

A motor which may be used within an appliance. The motor may include a fixed stator with a plurality of stator poles provided by electromagnets (e.g. wound coils) and at least one rotor. The activation of the rotor poles (e.g. the number of active rotor poles and/or the rotor pole switching frequency) can be controlled independent of the activation of the stator poles (e.g. the number of active stator poles and/or stator pole switching frequency). The motor may include multiple rotors connected in sequence to allow for increased fan speeds with relatively decreased dB level as well as a decrease in the size of the fan assembly.
