Selecting a VFD for a 1 HP Single Phase Motor

I am trying to locate a VFD to work with the attached motor.
It’s a single phase, 1 HP motor, and has a start capacitor. It will be wired to a BMS using a Digital Output to enable, 0-10VDC to adjust speed, and a dry contact for VFD fault input or drive status. Please let me know the product you recommend based on that info.

You need to check if the motor you're using is rated for variable frequency drive operation. If it's not, you could run into issues with overheating or damage over time. Do you have any info on that? Also, when dealing with single-phase motors and VFDs, it's usually better to replace them with 3-phase motors if possible. You'll get better performance and reliability that way.

Since your motor has a start capacitor, make sure the VFD you select can manage that. Not all drives work well with capacitors, and it can cause problems with performance.

I second the ATO suggestion. I’ve used their drives in similar setups, and they work great. Just ensure your wiring is correct, especially with the BMS and fault input, as that can sometimes be tricky to configure.

Thanks for the input, everyone! I’ll check out the ATO VFDs and take the capacitor issue into account.
