    Advantages

    Limitations

    Applicable Scenarios

    V/f Control VFD

    Maintains a constant ratio of voltage to frequency to ensure stable motor magnetic flux.

    Simple structure, low cost, high versatility, easy commissioning.

    Low torque at low speed, low speed regulation accuracy, slow dynamic response.

    Fans, pumps, conveyors, and other constant-torque/constant-power loads with low speed regulation accuracy requirements.

    Vector Control VFD

    Decomposes the motor stator current into excitation current and torque current, controlling them independently.

    High low-speed torque (up to 150% of rated torque), high speed regulation accuracy, fast dynamic response.

    Complex algorithm, high cost, requires accurate motor parameter input.

    Cranes, elevators, CNC machine tools, rolling mills, and other loads requiring high low-speed performance and dynamic response.

    Direct Torque Control VFD

    Directly controls the motor stator flux and torque without complex coordinate transformation.

    Faster dynamic response, strong anti-interference ability, high control precision.

    Larger torque ripple at low speed, slightly higher noise.

    High-performance servo systems, precision transmission equipment.
