Rotary phase converters are very handy pieces of gear for the shop and a cheap way to get 3 phase power. A Google search will give a better explanation but it’s a 3 phase motor, a way to start the motor (I use capacitors and a switch but there are easier/cheaper ways), and a connection from the motor to the equipment you want to run. Once the converter motor starts spinning it “makes” the three phase power. Again- a better explanation can be found on Google.

They can be made on the cheap if you’re resourceful. I watch local auctions and have purchased a few 3 phase electric motors for $1 per horse power. If you want to go much bigger than 7.5hp it’s good to have a cherry picker to move it around your shop. I have a 40hp electric motor that weighs 550lbs.

They can be sized to run 1hp to 100hp, just depends on the equipment you’re running. I run a 25hp converter for my shop and it has no issue powering any machines.

It opens up the door to professional equipment and better power.

If I had just one or two pieces of 3 phase equipment I would run them off a VFD since they’re a quick install and require very little wiring.
