Abstract
A brushless direct-current (BLDC) motor includes a stator assembly and a rotor assembly including a rotor supporting permanent magnets rotatable relative to the stator assembly. The stator assembly includes a stator comprising a stator core and stator teeth radially extending from the stator core and defining slots therebetween. A first set of stator windings is wound on the stator teeth, and a second set of stator windings is also wound on the stator teeth such that, on each stator tooth, the first and second windings are provided in an electrically parallel configuration.
