Tips: Choose a VFD base on motor rated current

When a motor power is stated, it is always the mechanical power, shaft power i.e. NOT the input electrical power.
Variable frequency drives (VFD) are also (mostly) rated in terms of kW albeit it's wrong. Because VFD output is electrical (not mechanical). Mechanical power (i.e. motor shaft power) is always "active" power, where in electricity we also have reactive (doing nothing but losses) power. The apparent (total) power (stated in terms of kVA) is vectorial sum of active and reactive power components.
For all those facts above, ATO highly recommend to select a VFD by matching motor current. This is the right way. Despite mathematically correct, we wouldn't select a VFD for partial load of motor. We would simply go for motor nominal (rated) current.
Finally the answer is: choose a VFD output current ≥ motor rated current.

How to run a three phase or single phase motor with ATO VFD on 120V power supply. Take a 2 hp, single phase 120V input, single phase or three phase 220V output variable frequency drive as an example. It shows you how to wire, set parameters, commissioning VFD, run motors, etc.

Existing reviews of 1 hp VFD, Single Phase 120V Input, 1ph/3ph 220V Output

1 hp VFD use

Do I need an additional relay to use with the 1 hp VFD, or can I connect it directly to the motor?

From: Garety | Date: 14/03/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Just connect the 1 hp VFD directly to the motor.

1 hp VFD delivery time

We are looking into 1 hp VFD, single phase 120V Input, 1ph/3ph 220V output drive to control a couple fans, want to make sure we can control these with a pressure transducer having 0-10v dc signal? Also what is the lead time if we order two?

From: Amanda | Date: 27/04/2021

Was this review helpful? Yes No (0/0)

ATO Responded

Yes, you can control the drive via 0-10V signal.
Total delivery time to your address: Approx 1 week after payment is made.

Questions about 1hp VFD parameters

For your 1hp variable frequency drives. Are the parameters saved when set, or is there a process to save them?

From: Deborah | Date: 08/11/2021

Was this review helpful? Yes No (0/0)

ATO Responded

The parameters are saved automatically when set.

Application Question

1. I am looking to drive a spindle motor at 230v with 3.3FLA. (1HP) . Should I upsize and move to the 2hp unit?

2. The table in the description listed rated current as 4 amps (7 amps for 2hp unit). Is this input or output rating?

3. What are the recommended feeder circuits wire gauge and breaker amperage for both this unit and the 2hp unit?

4. Do you recommend wiring in fuses before the VFD (i.e. slow blow fuse, etc)?

From: Matt | Date: 18/07/2022

Was this review helpful? Yes No (0/0)

ATO Responded

1. Yes, it is safer to use 2HP capacity.
2. 4A is the output rating.
3. 1.5mm square wire is enough. The current of the circuit breaker should be more than 2 times greater than the output current of the inverter.
4. A fuse can be added to the VFD input.
