More Information
Summary:An HVAC control system for a household central air conditioning, including an HVAC system controller, a centrifugal blower motor, a compressor motor, and an axial fan motor. The HVAC system controller includes an HVAC microprocessor, a sensor, an interface unit for motor control, a power supply part, and a signal processing circuit. The interface unit for motor control includes an inverter unit and a rotor position detection unit. At least one of the centrifugal blower motor, the compressor motor, and the axial fan motor is a permanent magnet synchronous motor in the absence of a motor controller. The HVAC microprocessor drives the permanent magnet synchronous motor in the absence of a motor controller via the inverter unit. The rotor position detection unit sends a rotor position signal of the permanent magnet synchronous motor in the absence of a motor controller to the HVAC microprocessor.
