What is a variable-frequency pump, and what are its functions and principles? Where is it generally used! What’s the difference from a centrifugal pump! Thank you!
Inverters are used with motors to change the motor’s speed by altering its frequency. The advantage is energy savings, while the disadvantage is the high price and large initial investment.
In fact, it is the frequency conversion of the motor. Frequency conversion requires a motor + inverter. In general industry, AC motors combined with frequency converters are used. An inverter converts alternating current into alternating current with the desired frequency and voltage, thereby changing the speed and torque of the motor and enabling frequency conversion of the motor. Motors used for frequency conversion differ from ordinary motors in terms of design, such as shaft current and winding overheating.
Our heating furnace’s exhaust fans and blowers use variable-frequency motors
