    Tips: Variable frequency drive noise and vibration problems and solutions
    When using VFD for speed adjusting, it will produce noise and vibration. This is because the VFD output waveform contains high harmonic wave. With the change of the operating frequency, the fundamental component and the harmonic component all change in a large range, which is likely to resonate with the inherent mechanical vibration of the motor, and the resonance is the source of noise and vibration.

    1. When the low harmonic wave components in the output resonate with the inherent mechanical frequency of the rotor, the noise will increases. When the high harmonic wave components in the output are resonated with the iron core, machine enclosure and bearing bracket at the vicinity of the respective natural frequencies, the noise will increases.
      The noise generated by the drive motor, especially the harsh noise, is related to the switching frequency of the PWM control, especially in the low frequency region. To solve this problem, usually connect AC reactor on the VFD output side. If there is electromagnetic torque margin, u/f can be set lower to reduce noise.
    2. When the VFD is in operation, the magnetic field caused by the higher harmonic wave in the output waveform generates electromagnetic driving force for many mechanical parts. When the driving force frequency is close or overlap with inherent frequency of these mechanical components, will resonate. The main effect on the vibration is the lower harmonic wave component, which has a greater impact in the PAM mode and square wave PWM mode. But when using SPWM mode, the low harmonic wave component is low, and the impact is also lower.
      The method of reducing or eliminating the vibration is to connect the AC reactor to the output side of the VFD to absorb the high harmonic current component. If still using PAM mode or square wave PWM mode VFD, switch to SPWM mode VFD to reduce pulsating torque, weaken or eliminate vibration, and to prevent the mechanical part damage due to vibration.

    Great VFD
    Unit arrived on time and as described.  It runs my 2hp milling machine very well. I'll be getting another VFD from you for my next piece of equipment.

    Excellent value for the money
    Purchased three VFDs of 2.2kW power rating, excellent value for the money. I'm using one of these to drive a 3 hp 3 phase air compressor I picked up for my home shop. I deal with a lot of VFD's in my profession. I wouldn't specify it for a critical industrial application yet but for home use it seems to work well.

    Technical info
    Good day

    I have a three phase motor that in the nameplate says 2 HP, 200-230 V, 7.6-7.8 Amps.

    Do this vfd is enough to control that motor, cause in the table of this vfd say rated current 6A, or i need the 5Hp? i saw the 2HP and i have the same question.
    For the motor i have which vfd is the correct one.

    Yes, it's enough, you need to choose input voltage with 220v, which has rated current with 10A.
    Questions about 3hp VFD
    Can I get an Inverter to run a 480 Volt 3 Phase, 3 HP Motor on 208V, 3 Phase?

    No, the opposite is correct, the output voltage cannot be lower than input voltage.
