3/4hp variable speed dc motor with control, from an untapped source

[BKtoys]

here are a few pics of my cnc lathe with a consew motor. all i did was take off the origanal switch and replaced it with a 2.5K pot this is my custom taig cnc lathe i built up from the bottom half of a taig mill. my mill is also a taig and it has a consew on it, but it is direct drive here are some pics. i got my motors from supersewingman on ebay his store is in Lairada Cal

i'm glad to see this is working out well for everyone I'm really happy with the one i installed on my 9x20 lathe
happy chips

well alright if you would I would like to know..does it have the balls on the lowest speed? also what do you like or don't like...I may just buy one for the heck of it before they go away....

its really hard to find good quality stuff today reasonably....


Thanks for sharing

Could one of these be plugged in to a router speed controller and then control speed, off and on, etc. all for the router speed control box?

i'm not and electrican but i would think no... the ac is converted to dc of a higher voltage then sent to the motor at up to 160 volts. reversing is done on the dc side of the circuit by just reversing polarity.

at the lowest speeds my motor lacks power but on my lathe i had removed a 1700 motor and installed this one that is about 4000 i think at my lower speeds with my belt reductions there is a lot of power because the motor is still turning around 1500 rpm. for a 100 spindle speed.

What's the verdict?
Are these motors holding up well in the shop, especially on the lathes? Any troubles appearing like overheating? I have a Grizzly G4000 with a dead motor and am thinking about replacing it with something like these to get variable speed. My shop is a garage with no A/C or heat. I'm concerned about dust also. Any input is greatly appreciated.

Thanks,
Lee

++hi Lee i have 2 of these motors one on my lathe and one on my cnc mill . I v'e both of these motors on my equipment for almost 7 or 8 months and i have ran them from 4 to 6 hrs a day. with no problems or over heating

Thanks for the report Brian. I appreciate you taking the time.

It sounds like these motors are a good idea.

I just went to the Consew site, it looks like some of the machine stands
might work for some smaller lathes? and come with the foot speed control, might make
controling speed easier, rather than going through a bunch of hoops.

Newbie alert !!

I need to replace the motor on my 9x20 and these motors look like a great option. Since the motors I looked at were 3/4" shafts, can I get away with just boring the original motor pulley ? How about drive belt length ? Some pics of everyone's setups would be very much appreciated.

Okay, well this isn't a 9x20 and it's rather half-assed, but it is a sewing machine motor and it works fine for now.
