Application of VFD in Realizing Motor Soft Star
The hard start of the motor will not only cause a serious impact on the power grid but also require too much power grid capacity. Additionally, the large current and vibration generated during start-up will cause great damage to the baffle and valve, which will reduce the equipment service life. After using VFD, the soft start function of the inverter will make the starting current change from zero and the maximum value will not exceed the rated current, which reduces the impact on the power grid and the power supply capacity so as to prolong the lifespan of equipment and valves and save the maintenance cost of the equipment accordingly.
- The first section of VFD (variable voltage control) not only converts the AC supply voltage into DC but also controls the required pulsating DC output voltage to maintain V/f constant ratio by using SCR/IGBT rectifier.
- The second section of VFD (DC-Link/DC Bus) consists of inductance and capacitors to convert pulsating DC into pure direct current. Here, inductance smooths the current, and the capacitor smooths the voltage.
- The third section of VFD (referred to as variable frequency control) not only converts DC voltage back into AC voltage but also controls the variable frequency to maintain the V/f ratio by using electronic devices such as SCR/IGBT transistors.
- Cooling method-forced air.
- Keep away the ac converter from corrosive gasses, liquid, moisture, and dust.
- Installation location altitude below 1000m (In the case above 1000m, VFD is to be de-rated. Please contact for technical support).
- Storage-temperate -20℃ to +60℃.
- Ambient temperature -10℃ to +40℃ (non-condensing and not frozen).
- Ambient humidity below 90% RH.
- Vibration under 20Hz 9.8m/s(1G), over 20Hz 5.88m/s (0.6G).
- V/f (volts per hertz) or V/hz control.
- V/f with encoder or closed loop V/f (PG card).
- Open loop vector control.
- Closed loop vector control (PG card).
- VFD capacity is to be sized more or equal to the sum of the capacity of all connected motors.
- The sum of the distance between the VFD and all connected motors should be less than 500m. Introduce an output load reactor to avoid motor failure due to voltage spikes, current surges, or harmonics.
- Install circuit breaker MCB or with extra protection MPCB between each motor and VFD.
- The voltage of each motor should be the same and ensure the VFD adoptable current is higher than the sum of all rated currents.
- Connect all motors with VFD output in parallel.
