  • Patent number: 11716002
    Abstract: A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly may include a stator assembly with multiple coils in a distributed winding configuration. The stator assembly may have a central bore into which a rotor assembly having multiple poles is received and configured to rotate. A method of controlling a switched reluctance motor may include at least three phases wherein during each conduction period a first phase is energized with negative direction current, a second phase is energized with positive current and there is at least one non-energized phase. During each commutation period either the first phase or second phase switches off to a non-energized state and one of the non-energized phases switches on to an energized state with the same direction current as the first or second phase that was switched off. The switched reluctance motor may include a distributed winding configuration.

  • Patent number: 10940280
    Abstract: A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, a shield portion including an outer edge substantially aligning with or extending beyond an outer edge of the impeller, and a motor adapted to drive the impeller. The housing and the stationary component cooperate to define a volute that directs air towards the outlet, and the housing includes a separating wall constructed and arranged to divide the volute into a high speed airpath region and a low speed airpath region. The outer edge of the shield portion and the separating wall define a gap between the high speed airpath region and the low speed airpath region.
