The power of single-phase 110VAC motors is generally small and has little impact on the power grid, so VFDs are generally not used. In addition, in terms of speed regulation, it is not recommended to adjust the speed of 110V AC single-phase motors, which has a lot to do with the structure of the motor.
Will this run a 120v 60 Hz, single phase motor with BOTH start & run capacitors at 40% speed? Will the start capacitor circuit need a switch to keep from burning out? Does the unit somehow protect non-VFD rated motors from overheating the insulation?
It is uncertain whether the internal centrifugal switch of the motor will automatically cut off the connection of the starting capacitor at 40% speed. Some motors can only be separated by 80%.

Yes, www.ato.com/120v-vfd However, I do not recommend running the motor at low speed for a long time because the heat dissipation performance of the motor will become poor. It is recommended to keep the motor running speed above 65%. Note that VFD cannot exist in high humidity environments.
higher than a 3 phase motor replacement if available. Single phase motors are built cheaply ie. not built for control flexibility 🙂 ("you get what you pay for"... cheap is super limited LOL)
Centrifugal SW issue .... continued: Solution: I guess the motor must be restricted to operate above " Centrif.SW Speed" besides the soft-start ramp else everything fries, right? The best trick would be to programmatically kill the start winding output after 3 secs or with a matched potential relay... hello headaches.
@@ATOcom An additional switch or relay would have to be installed to prevent the starting capacitor from turning on at lower RPM and work as normal on start-up. You don't just remove the capacitor...
Question : so how is the Start Winding problem managed with this VFD?? I understand the problem is that this 90° winding CAN NOT be energized non-stop but shortly during ramp-up (then cut-off by centrifugal switch in serie with capacitor) because it's wire diameter is too skinny and it's phase is PURPOSELY SHIFTED ONLY TO KICK rotor in one direction. During runtime the 90° startup phase partially opposes rotation!!! FYI: in refrigerators and AC compressors the start winding is disconnected by a "starter PTC" or "potential relay" that precisely senses run current. Be curious: try this... bypass the centrifugal SW to keep start winding + cap powered non-stop. Outcome everything quickly gets real toasty destructive - Well this is exactly what happen when the VFD runs below centrif SW speed!!!
I turned the sound completely down because of the annoying music.
do you make any 1 phase 110 in 1 phase 110 out vfd? if not why not?

can this VFD increase the frequency beyond the input frequency>
Will this work for the following conditions.
Input 120 Vac 60hz
Output 230 Vac, 53 to 133hz, 1/3hp, 3.3 amps
What is your load?

Is there chance that invertor with 220v single phase output run three phase motor? Thanks
Only 3-phase output VFD is possible, but we have single-phase input to three-phase output VFD.www.ato.com/single-phase-to-three-phase-vfd
Will this work on single phase, PSC , fractional HP motors. I want to slow the blower speed on my AC during high humidity.
Yes,

If I want to run single phase motor with VFD it already supply 3phase ac motor. What will Ido?
Did you order the VFD from ATO?
Where is the FE-03 setting in the VK3000 manual?

Can I use this VFD with 120VAC input and drive a 120VAC induction (pump) motor? If not what?
Can't drive 120V motor.
what is the cost of this unit?

hi, can this inverter model be mounted on a 220v, 2cv, 1.5kw powered motor?
What model do you need?

AC220V input，AC220V output 1 or 3 phase，www.ato.com/single-phase-vfd
Hello all,
Can we run 220v 3kw motor with 120v input? Single phase.
YES, www.ato.com/5hp-vfd-single-phase-120v-input-1-phase-3-phase-220v-output
so if i get a 110 input vfd do i have to run it with a 110v motor?
This VFD is advertised as using 120V single-phase input but up to 240V output, single-phase or three-phase.
Can I use this VFD to convert 1 phase 220v 50hz input to 1 phase 120v 60hz output
NO...
@@ATOcom what's the solution?
@@mikefreedom5612 You can add a transformer (220V to 120V) before the VFD input. The VFD can change the frequency to 60Hz.
