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.
A control system for an induction motor configured to adjust a slip frequency of the induction motor based on a measured characteristic of a flow of fluid produced by a rotating rotor of the induction motor.
A control system for an induction motor in a blower, the blower comprising at least one impeller coupled to a rotor of the induction motor and configured to generate a supply of pressurized fluid, the control system comprising
A method of controlling a rotor speed of an induction motor by determining a slip frequency based on a measured characteristic of a flow of fluid produced by a rotating rotor of the induction motor and adjusting a stator frequency as a function of the determined slip frequency.
A method of controlling a speed of an induction motor in a blower configured to provide a supply of pressurized fluid, the method comprising:
