    Tips: Variable frequency drive development trend

    1. Low electromagnetic noise and mute
      In addition to using the high frequency carrier sine wave SPWM modulation to achieve low noise, the VFD input side plus AC reactor or active power factor correction circuit APFC, and the inverter circuit also using SOFT-PWM control technology to improve the input current waveform, reduce the harmonic wave of the grid. The VFD meets the EMC international standard in anti-interference and inhibits the higher harmonic, and to achieve clean energy conversion.
    2. Customization
      The new VFD in order to better play the unique function of frequency control technology, and as far as possible to meet the needs of field control, derived from a number of customization models such as fan water pump air-conditioning dedicated model, heavy machinery dedicated model, AC elevator dedicated model, textile machinery dedicated model and so on.
    3. Systematic
      In addition to the development of digital, intelligent and multi-functional, the VFD is also developing to the integrated and systematic direction. The purpose is to provide the best system functions for users.
    4. Network
      The VFD can provide a variety of compatible communication interface, and can support a variety of different communication protocols. The built-in RS485 interface is able to input operation command and set the function code data from the computer.

    Factors affecting the shortening of VFD service life
    I have been told that using a VFD with one phase motor shortens the lifespan and also runs the motor hot. Does this 300 hp VFD not have those issues?

    No, most of modern motors works fine. Any way the motor will work very good with the VFD if the motor is VFD duty. So, it depends on your motor specs.
    Operating temperature of VFD
    If I'm going to use a 7.5 hp 230v 3 phase motor and the input is 240v single phase, will the 7.5 vfd be sufficient or will I need to upsize VFD. It will be installed in a garage, so it will have to deal with the summer heat and cold winter ambient temperature. Continuos duty.

    Generally, make 15% oversizing. And our VFD temperature range: –10℃~ +40℃; VFD will be derated if ambient temperature exceeds 40℃; each rise 1℃, the derate will be 5%.
