    What did you want to cut? The Chinese spindles on Ebay generally go quite fast, which is fine for wood and plastics, but not so good for metals. They are way too fast to use as a motor on the standard Taig; the bearings aren't rated for more than 10k rpm. But the standard Taig motor won't work well on 50hz current, which you use there. I generally advise European clients to purchase a Taig without the motor, and source one locally. You'd want one with close to the same specs: totally enclosed, fan-cooled, continuous duty, 3450 rpm, and 1/4 hp or better induction motor. That shouldn't be too hard to find. But if you really want variable speed, what about something like the Sherline DC motor, which comes with a speed controller: 33050 DC Motor and Speed Control Units — Sherline Products ?

    I´m carving and engraving in wood, so I was looking for a spindle with easier speed regulation than the belt moving on Taig and with the same speed range. I have used the original Taig now in several years on 50Hz without any other problems than some sparkling noise issues.

    People have repurposed treadmill motors to run their spindles; the trick is to find one that's light enough. If you use one of those Chinese spindles, the speed range won't be the same. They give you a top speed that's about twice as fast, but the lowest speed of that spindle will be close to the top speed with the regular motor. Go much slower, and the torque falls away to nothing, while the fan stops providing any cooling. But if your regular motor works okay for you, save that for jobs that need slow speeds, and mount a dovetail to the back of the high-speed spindle so you can swap it in easily when you need to spin fast.

    Deepgroove1 has spindle motor setup. Consew makes a brushless servo motor for controller that are all over ebay. I have been using a treadmill motor with a kb controller running with the taig step pulleys. I have a consew motor sitting on the bench it has much more torque then the treadmill, but the treadmill motor has a higher rpm. Not that it is recommended but I can spin the spindle at 18000 with the treadmill motor, I usually keep below 10,000 rpm.

    tread mill motor
    consew motor
    if you need more power

    deepgroove1
