    What is the price of this sewing machine motor? I found another with 400W engine for Euro 93.-

    I heard there is a way to make them spin faster on the controller. Mine goes up to 4200rpm, do you know how to make it go faster?

    Yes, something like that, too. but the specific schemes not caught. I think you can just the pulley on the spindle to change for reduction 1:1. Or 1:2. pulley is very cheap (3-5 usd). Auroras max rpm default 4500.

    You can adjust the upper speed limit of the Consew motor through the menu system. Just depend on which version you are using as to the process. Mine has the four digit, four button panel. Once you get the top speed showing on the menu, I just push the up arrow which adjusts it up to 7000 RPM. But I've only been about to achieve 6500 RPM consistently. Using a quadrature encoder for feedback to UCCNC via a UC300ETH which gives full PID control over the spindle. It nicely holds within 10 RPM and ramps up when taking deep cuts. Pics and vids of my setup, how I setup software control and the encoder are on the Taig Facebook Group.

    What about the 900W motor in Kenwood chef Kitchen machine. Are there anybody here who know how much rpm. they have on fastest speed? I believe these motors must be easier to obtain than sewing machine motors..

    quicky question here: I bought the deepgroove brushless upgrade and it is shrill sounding, enough to wear out my ears for anything running more than 5 or 10 minutes, INSIDE A CUSTOM BUILT SOUND-BOX I BUILT! Does anybody else here have experience with this motor? I'm not getting good support from deepgroove on this (his only reply is that these motors have not had a failure problem in the many units he has sold, which says nothing about the noise. It actually sounds like worn out bearings and has lots of micro-stutters. I have a recording if anybody wants to give a listen.
    thanks for reading.

    Good luck with any support from her/him whatever he is now. That is an overpriced kit and same parts can be had on Amazon for 114ish for motor and 10 bucks for an XL 20 tooth for spindle and XL40 tooth for motor. You just need to bore them yourself.

    Sound like the motor bearings are bad (common issue and why I bought from Amazon for easy returns). If you paid with Paypal, they will pay your return shipping....get you money back and make your own. Tons of info on belts/pulleys/motors on the Taig FB group. I have switch to a DMM 750W Servo myself.

    I really don't like Facebook. Any chance of getting a quick summary here of how you are injecting the speed control signal from the CNC control into the motor controller?

    Are we talking the Consew controller or DMM?. Also which board are you using for speed control? If it outputs a 0-10v signal, your best and safest bet is to buy a KBSI-240D as it gives isolation and zero/span adjustment pots. You can find them used on ebay for 30 bucks or less if you keep an eye out. Their becoming quite popular again with all the folks using these controllers which have signal voltages referenced at main voltage levels. Look for one with a green pcb board and not the really old white board.

    There are also two or three options from CNC4PC. A C69 board, a C11G board and one other variant of these I can't remember. These give you isolation, but only a single trim pot. So you have to tweak the duty cycle to get your startup voltage to the 1.7v where the Consew starts and use the pot for the upper end of 4.8v. All controllers vary a little. FYI if it's the 4 digit display model, you can run the speed up on the controller to 7k RPM, but it was never stable for me above 6500 RPM. And just remember the 0-5v signal is 170v-175v, that's what kicks the crap out of most people and fries their board if they use any earth common with speed control.

    If it was DMM their manual is good.

    Forums are dying. I hate FB too. Just makeup a name and use it, otherwise it's your loss since almost all info now goes there for the most part. I try to post a few things over here when I can, but just don't have the time mostly.

    Good luck! And get a DMM when you can. I love mine.
