What is the difference between air conditioner speed regulation and electric fan speed regulation?
The difference between them is reflected in the range of speed regulation with a fixed torque load. Two, the motor efficiency is reflected at different speeds. Three, the torque is expressed at different speeds.
Variable frequency air conditioning is to change the frequency of motor power supply to achieve speed regulation, in fact, the frequency adjustment will also change the voltage.
Inverter air conditioners and fans are asynchronous motors (not sure if there are any other types, but common ones). The fan is single-phase and the air conditioner is multiphase.
