摘要： The present disclosure relates to a method of controlling a poly-phase switched reluctance motor assembly, the poly-phase switched reluctance motor comprising at least three phases, the method comprising: during each conduction period energizing a first phase with a negative direction current, energizing a second phase with a positive direction current and having at least one non-energized phase; and during each commutation period switching off one of the first phase or the second phase to a non-energized state and switching on one of the non-energized phases to an energized state with a same direction current as the first or second phase that was switched off.

摘要： A method of a control system (2200) controls an inductance motor in a blower including an impeller and volute using a pressure compensation control system. The control system may be implemented in a respiratory pressure therapy device. The control system may include a sensor configured to provide a pressure signal indicative of the pressure of a flow of fluid produced by the blower. A measured pressure may be compared to a set pressure to determine a pressure error. A slip frequency may be adjusted as a function of the pressure error in an attempt to eliminate or minimise the pressure error.

摘要： A stator assembly has coils in a distributed winding configuration. A poly-phase switched reluctance motor assembly 3002 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.
