Baldor 1022W

[greg86z28]

Does anyone have experience with the 1022W?

It's a 1hp, single phase, 1800 RPM, 10" grinder. I noticed the amp draw seems sort of low at 5.4/2.7A.

I think the older version of this model has a higher amp draw (9.4A on 115V).

Thanks,

Greg

Something fishy there. 5.4 amps at 120vac would indicate the motor is more like 1/4 hp.

 

[greg86z28]

Well I think it's 120V*5.4A = 648 Watts = 0.87 hp (assuming no losses).

 

[Dingleburry]

745 watts is 1hp
5.4A x 120V = 648 watts / 745 = .87hp
2.7A x 240V = 648 watts / 745 = .87 hp
Maybe over rating it a bit but its deff not 1/4 hp. And alot closer to 1hp.

The old one you claim thats 9.4A
9.4 x 120 = 1128 / 745 = 1.5hp

I'm not 100% confident in that figure, I found it online so I'm taking it with a grain of salt.

Anyways, do you guys think this is a decent grinder?

Guy is asking $500 OBO including what I think is an original stand. It has the basic shields not the nice heavy duty lighted ones. Looks to be in nice shape.

I dont know if its a decent grinder but its list price is 1500usd

That's about as good as bench grinders get. New without base is around $1100 so the price is not out of line if it is in good condition. I'm cheap though and I would be looking for an old Wissota for a lot less.

Weird...literally the last company I'd expect to inflate HP #s. Very few electrical things are 100% efficient, and even if that were the case here, it's still less than 1HP. Probably a pretty nice grinder though. Can you try before you buy? Do you really need a 10" grinder? $500 is a decent chunk of dough - with that budget you can probably get something new and/or more powerful (i.e. Jet industrial [gray], etc.).

You're assuming 100% efficiency which ain't even close for a small single phase motor. 0.87 x 0.67 is gonna be in the ballpark so just north of 1/2HP.

It's also fishy that they're claiming 1,800 rpm which ain't happening with a conventional motor. I guess it's possible it might be ECM or inverter either of which would boost efficiency some. Maybe boost it into the 3/4HP range best case.

Unless they're doing it differently, full load amp rating is typically what's listed for a motor in product specifications. For a 1hp motor at 120vac that would be 16 amps, for a 1/4hp motor that would be 5.8 amps.

I agree that efficiency needs to be included in the voltage x amps calculations, if that's how they are listing it.

 

[greg86z28]

I was surprised. I think Baldor is highly regarded as a USA made overbuilt product. My assumption would have been they state 1 hp and you likely get 1.1 hp (or something like that).

I really wanted a solid built to last USA model - even though it's probably overkill for what I need.

10inch grinder doesn't take off more material then an 8inch.

if i was gonna pay 500$ for a grinder id get one of them with a belt grinder setup for material removal.

instead i am building a 2x72 belt grinder instead of using a 8-12inch hard wheel grinder.

 

[greg86z28]

This one is pretty far away from me anyways so I'm going to pass.

But thanks for the info!

I had a 1022, it was a beast. You won’t find a better grinder than Baldor.

 

[seber]

By law a 4 pole 3/4 to 1 hp motor must be at least 82.6% efficient. Four pole single phase motors run at 1750 to 1800 rpm as built. 648 watts x 82.6% = .715 hp. My guess is that this unit is capacitor run which can increase power output on a temporary basis. Still, not a true one hp.

 

[Dingleburry]

Maybe its got efficiency already factored in. I tested my .5hp in the shop, no load only wire wheel, and grinding disc
Data plate says 3.4A for .5hp @ 115v.
Clamp meter is 2.5A no load, 3.4 under what i wouod consider a light load
5-7A under heavy load, and can still rotate no problem.
3 4A is .52hp,

Edit. Oh its also a baldor.

I have an old 1022W. It is a beast and does claim 1800 rpm. I can't access the tag right now to check the draw. I paid $60 at a school auction 20 years ago. It came with one lighted guard and both rests.

10inch grinder doesn't take off more material then an 8inch.

+1
In fact, the surface speed on a 8-inch grinder is typically far greater than a 10-inch. Most 8-inch run at 3450 rpm, while every 10-inch I've seen is half that. But a slow very coarse wheel can remove metal pretty damn fast.....

 

[seber]

Actually, a coarse wheel running at low speed will catch and remove material faster than one running at higher surface speed up to a point. It will also do a lot less heating as each grain removes a larger chip.

I bought this Baldor 1022W from a farmer about 8 years ago. I paid $300 for it and have been very satisfied with the purchase. It has plenty of power for anything I have used it for. Here are some pics.

 

[930dreamer]

I have an 8102W in 3 phase, works very well.
