Help with A/C motor rewire

[tackytony]

Hi - I recently picked up a gently used Jointer. It's pre-wired for 220, but looks to be able to be wired for 110, which is what I need in my rental garage.
I think I have the re-wire on the motor done correctly. At least, it looks correct based on the diagram on the motor. But all I get is a loud humming when I try to turn it on. So I looked at the switch on the machine and can't make heads or tails out of it. Can someone look at the pics and give me a hand?

You got a few things going on here.

At 120V the motor requires 24A, not going to run to well on a 15 or 20A circuit if at all.
The motor starter overload is too small to adjust for the 24A and it will be damaged by running an overcurrent through it, its max rating is 20A
Thirdly the magnetic coil in the starter is rated for 230V and will not work properly at 120V, its likely to burn up with repeated application of 120V.

You would need to change the starter to something rated for 120V control voltage, and big enough to be rated for the 24A nameplate current. Even after changing the starter and cord size your storage building outlet may not be big enough to get it started, let alone take a decent cut.

1HP is about the biggest motor you can reliably start and run off of a normal 120V outlet.

I'm sure that's not what you wanted to hear, but it is what it is. Continued trials at low voltage is likely to cause damage. It also appears that your terminal connections are correct for low voltage operation. The no start is the result of low voltage, and high current.

Hmmm... I was wondering if that was the problem. ****. Well, thanks for the input. Really appreciate it.

The voltage drop is probably pretty high while starting and therefore the voltage isnt high enough to start the motor.

How long is the wire run?

This is a detached garage from the 50s. Wires run probably 30 feet from panel on house to outlet in garage. After looking, the circuit breaker is only 20A going out to the garage. Clearly I have a power supply issue with this 2HP motor.
I've already talked to the owners about putting in 220, and it's a no go. So, guess I won't be using this machine at this place. Bummer.

Thanks for the help, though!

U could get a transformer to step up the 120v to 240v...
