It sure sounds like you need a line reactor on that setup. Does this load cycle frequently? Do you stop the load by sending the stop command to the VFD, or opening the line side contactor? Here's a good read on line and load reactor basics.

Here's a good post on 2-speed motors. https://precisionautomation.net/2019/04/05/a-primer-on-two-speed-motors/

I am trying to understand 2 speed induction motors, so I figured the 2 speed, 2 winding, 3 phase induction motor would be simpler to understand. From what I learned in my electrical engineering classes a few years ago, the more times a conductor is wound, the stronger the magnetic field and thus...

Does anyone know what door/window sensors go with DSC Power 1832? I believe that Sentrol's 1086 series would work but wanted to make sure. https://www.valinonline.com/products/1086t-n Can someone please confirm?

https://www.valinonline.com/products/esv152n02txb drive is listed as three phase only 2 HP. I want to use it to power a 3/4 HP 3 phase South Bend lathe. The literature says it will throw a drive fault for phase loss, is there a way to override this? I have not tried it yet due to wanting to do a...

Here's a link to Sentrol's 1125 series. It says Edwards Signaling on this page, but the sensors I have says Sentrol. All the specs seems to be exactly the same. https://www.clrwtr.com/Products/1125-N

I used to power it with 230V 3 phase, but I am running out of a residential garage now, so the static controller will not work. I assume I will need another controller. I am not sure about 230v single and 3 phase, although from what I have read the 230v available in a residence will be single...

Our home has an ADT Safewatch Pro 3000 security system, with the front entry door having sentrol magnetic switch hard wired into the door frame (installed in 2009). http://www.clrwtr.com/PDF/GE-Security/GE-1085T-Series-Magnetic-Contacts.pdf We had the front door with frame replaced and want to...

Thank you for the replies. My VFD is an AC Tech. http://shop.actechdrives.com/AC-Tech-Lenze-ESV152N02YXB-p/esv152n02yxb.htm

I have been looking at a couple of power tools that have a 220v 3 phase motor. I was wanting to avoid having to install a rotary converter. But I have been told the VFDs that some folks use are bad for the motors and can ruin them. Can you share any insight into this? Thank you in advance...
