Description

Technical field: [0001] The invention relates to an electronic commutation motor, a control method thereof and an applied HVAC debugging system. Background technique: [0002] Such as figure 1 As shown, the five gear positions L1, L2, L3, L4, and L5 of the existing electronically commutated motor are respectively connected to the 24V AC signal input. When any line is powered on, the interface circuit sends the gear position signal to the microprocessor. , the microprocessor controls the electronically commutated motor to run at a certain speed through the inverter unit. [0003] Electronically commutated motors used in HVAC systems, due to differences in air ducts (different static pressures) during actual installation, the air volume or torque set by the motor factory is not suitable for the situation on site, and the output torque or speed of the motor needs to be adjusted on site to achieve the desired air volume. The above-mentioned electronically commutated motor str...
