摘要： A blower includes a housing including a proximal opening and a distal opening that are co-axially aligned, a stator component provided to the housing, an impeller positioned between the proximal opening of the housing and the stator component, and a motor adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.

摘要： A respiratory treatment apparatus generates an indication of inspiration or expiration based on a measure of motor current of a flow generator. In an example, first and second current signals are derived from the measurement. The first derived current signal may be a long term measure or average of current and the second derived current signal may be a short term measure or average of current. A processor 120 determines an indication of inspiration or expiration as a function of the first and second derived current signals. The function of the first derived current signal and the second derived current signal may be a comparison of the derived current signals. The derived signals may be determined by filtering. The indication of inspiration or expiration may serve as a trigger or cycle control for changing treatment pressure in synchrony with patient respiration without measured signals from pressure, flow or speed sensors.

摘要： 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.
