Baldor 575 volts

Sirs: Will the above Baldor M3558T-5 motor work on 110 Voltage at my home?
The voltage listed on the motor is 575
Let me be the first to say...NO
Another problem is that it is probably 3 phase and your house is single phase
Looking up that motor spec, I only see that it's rated for 575V and not configurable for any other. If indeed it cannot be rewired for 240V then it's not much good to you.
If the motor was free, AND I already had a 240V VFC (with single phase input and 3 phase output), then you could, in theory use it, but at much reduced rating....
You could lie to the inverter and set the inverter up telling it that the motor nameplate is:
240V, 25Hz, 726RPM, 0.83HP. The motor might be rated at 2HP but it is a constant torque device, designed to be operated at 60Hz and 575V, so you get the full torque at 25Hz and 240V, but not full HP... There is also the concern running it that slow of reduced cooling fan flow, so it would be OK for short duration uses but might overheat for continuous use. Many non VFC motors are not rated for continuous operation below 50% speed...
Seriously though, the best method would be to sell the motor and buy the right one for your application.

Oh, now I see you're from Canada... That might be why you're asking about the 575V 3 phase motor?? 575V 3 phase is uncommon in the US, and only slightly more common in Canada. In the US I've only seen it in large factories in the paper and steel industries. You could use a single phase boost transformer to boost 240 up to 575V, then purchase a 575V inverter.... But the 575V inverters are harder to source and more expensive... plus you'd have to buy the transformer. Even if the motor were free, I'd still purchase a new 240V single phase motor if you didn't need variable speed.

Gentlemen: Indeed, I am in upcountry Canada.
Thank you so much for your speedy response and guidance. I have absolute zero knowledge. There was a local seller selling this for $45 and I thought perhaps it would come to use for me at my home garage, but then when I closely read the specs it read at 575 volts. All I have seen is 220/230 volts, hence I was wondering if this would be of any good to me. So I will have to stay away from it cause in my garage I just have 110/220.
Thanks once again for the guidance.
Merci,
D

575 volts is the utilization voltage for 600 volt, three-phase power. The other 25 volts is an allowance for voltage drop under load.
So it is a common voltage industrially, but not for residential.
One note to add, 600V is common in Canada, not so much in the US 480V is more prevalent.
I run about a half dozen 550 to 575 V machines in my shop. The up front investment on average is about $2000 if you are electrical savvy and could Run you about $10,000 . Depending upon your KVA requirement for transforming power? I don’t want to get into this too much here because anything over a certain voltage. 150 V to ground distributed requires a certain license and is not permitted in most residential buildings... So the motor you got, is almost useless unless you know what you’re doing safely.
This is called a 600 V feed. What is your comfort zone handling these voltages?
Edit; I’ve helped build/set up many guys shops safely and to code. Some guys want to bend the rules and want to call it a temporary set up under generation code. I advise them, of just rules.
