摘要： An insulator for a stator assembly includes at least a first insulator adapted to be mounted to the stator core and structured to insulate the stator core from the coils. The at least one insulator includes structure to perform at least one additional function. For example, the structure may include a support member to support and/or locate the PCBA on the stator core, a wire guide to guide cross-over wires that form a connection between coils, and/or positioning structure to precisely position the PCBA with respect to the coils.

摘要： A blower includes a stationary portion including an inlet and an outlet, a rotating portion provided to the stationary portion, and a motor adapted to drive the rotating portion. The inlet and outlet are co-axially aligned. The stationary portion includes a housing, a stator component provided to the housing, and a tube providing an interior surface. The rotating portion includes one or more bearings that are provided along the interior surface of the tube to support a rotor within the tube. In an embodiment, the blower is structured to supply air at positive pressure.

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.
