    ACI V/F Control Blower Variable Frequency Converter


    V/F control type fan frequency converter is a type of frequency converter that controls motor speed by adjusting the ratio of output voltage to frequency (V/F), especially suitable for speed control of fan loads. The core principle is to maintain a constant magnetic flux in the motor, achieve speed regulation by changing the frequency, and adjust the voltage to maintain a stable V/F ratio.


    Working Principle

    • Constant magnetic flux control
      Below the rated frequency, by maintaining a constant voltage to frequency ratio (V/F), the motor's magnetic flux is ensured to be constant, avoiding weak or magnetic saturation.
      Above the rated frequency, the voltage is usually kept constant and only the frequency is adjusted to achieve constant power speed regulation.
    • Voltage controlled oscillator (VCO) for frequency adjustment
      The frequency converter converts the input voltage signal into a frequency signal through a voltage controlled oscillator, controls the frequency of the output voltage, and thus adjusts the motor speed.
    • Torque compensation mechanism
      During low-frequency operation, the output torque will decrease due to the influence of motor resistance. The V/F control frequency converter increases low-frequency voltage through torque boosting function (such as automatic torque boosting or manual torque boosting), compensates for insufficient torque, and ensures that the motor can still output sufficient torque at low speeds.

    Characteristic

    • Simple structure and low cost
      No need for complex current sensors or encoders, only need to adjust the output voltage and frequency, suitable for cost sensitive application scenarios.
    • Moderate speed range
      The usual speed regulation range is around 1:10, suitable for loads such as fans and pumps that do not require high speed regulation accuracy.
    • Open loop control, average response speed
      Due to the lack of feedback signals, the system response speed is slow, but it can meet the smooth speed regulation requirements of wind turbine loads.
    • Significant energy-saving effect
      By adjusting the motor speed to match the load demand, the motor can avoid long-term full speed operation and reduce energy consumption.
