    Hmmm. I use an industrial sewing machine and some of these brushless motors have zero torque. There are some new versions now that make substantially more power for punching through leather etc.

      @@GTIFabric good point, but lathes rely on speed more than torque. Especially on small lathes - yes, torque would be nice for heavy cutting but the lathe m6 leadscrew would shear off... So I opt for higher speed and 0.1-0.05mm depth of cut.

    I was also thinking of actually making a foot-pedal on mine to have both hands free while starting-stopping the lathe. Maybe both hand/foot switchable. With some work it is just easier to have the hands free to setup and hold and start the motor directly.

      My thoughts exactly, but a foot pedal is a hazard. If your foot accidentally touches it things start fling. My foot pedal is far from my leg-space (I actually have to take my leg out from under the table - and still I had mishaps. Maybe a combination of both will be good :)

    Thoughts on using a treadmill motor?

      For a large lathe - sure... why not?
      A friend of mine built a belt sander with a threadmil motor. Works just great.

    I've been thinking the same thing since I saw the Tested video with Adam Savage. I have a Unimat 3 and a Sherline with the original underpowered motors.
    How is the torque at low speed?
    Do you have measurements for the motor and mounting?

      Good question!
      My current el-cheapo motor absolutely lacks power. Lately I've been turning some bronze and boy does it need more mojo!
      This one is supposed to be much better:
      Voltage: 220V
      Frequency: 50Hz
      Power: 550W
      Speed control: 500-4500R/MIN
      Angular moment: 6N.M
      These motors are available on aliexpress. I'll add a #notsponsored and no affiliations link below. You can look up whatever alternative is best for you (I've seen 1000W motors).
      This one looks identical to what I have:

    Super! How does it work if you position the rotary wheel directly concentrically on the axis of rotation? Is it then not possible to regulate finely enough?
    Did you check here:
    ruclips.net/video/qao7Rex1lZU/видео.htmlsi=SFODKuFiVdUz-K3O
    ?
    I ask myself: Is there really no non-contacting rotary, cylindrical hall effekt sensor with the same eletrical values as the original linear hall effect sensor 49E?

      @@marcoam2610 hi. Well, very good question. I found no problems running it concentrically. You do need to slow down speed before you stop the motor or it stops instantly with a sharp impact. Other than thus it's not a problem
