Tips: Difference between VSD, VFD, ASD, AFD

The most correct term - according to IEEE and IEC - is ASD (Adjustable Speed Drive). This refers to the electronic equipment used to regulate the operating speed of the motor and driven equipment by controlling the frequency and voltage applied to the motor.
NOTE that other terms in common use include (but are not limited to): VSD (Variable Speed Drive), AFD (Adjustable Frequency Drive), and VFD (Variable Frequency Drive), they are referring to the same motor drives, just different names.
There is no difference between a VSD and VFD in terms of what it is designed to do. There MAY be differences based on specific internal components/construction and how it achieves that goal.

Existing reviews of 7.5 hp VFD, Single Phase to Three Phase VFD

Recommend a suitable VFD

We are looking for single phase input and output VSD for single phase fan 230VAC, 0.4kW. Could you please advice.

ATO Responded

Yes, recommended drive model: GK3000-1S000, 1 hp (0.75 kW) power capacity.

Do you provide reactors for 1-phase VFD?

We are looking forward to using your 1-phase VFD for a wall pump application. The pump motor will be about 180 meters from the VFD and your VFD manual says to use line reactors if the motor is more than 100 meters away. Please advise if you provide reactors for 1-phase.
VFD.

ATO Responded

Yes, we provide, and usually when the distance between the VFD and the motor is more than 100m, a reactor is required to be installed at the output.

5kW Aircon Application

Here's my problem; I bought a 5 kW 220V aircon which is 3 phase but the power provision is single phase; Can I use VFD for converting single phase into 3 phase? Any recommendation or suggestion is highly appreciated. thanks
