What is the meaning of double frequency conversion motor for large boiler fan?

Refers to the motor with rated load running continuously in the rated speed range of 100% ~ 100% under standard environmental conditions, and the temperature rise will not exceed the rated allowable value of the motor.

Frequency conversion motor is a kind of synchronous motor, and its speed is related to the frequency of power supply. In addition, a frequency converter is used to convert 50Hz power frequency alternating current into alternating current with variable output frequency.

The AC speed regulation mode of "special frequency conversion induction motor+frequency converter" has greatly improved the degree of mechanical automation and production efficiency, miniaturized the equipment and increased the comfort, and is now replacing the traditional mechanical speed regulation and DC speed regulation schemes.
