    I would take a different approach for this size lathe, and it all comes down to availability of motors in your location and shipping costs to your location. Some/most of the US eBay vendors do not...

    WEG's are OK, although I haven't done any installs with them (just helped a few others that have used them). I do not recommend the Teco L510 for lathes because it does not support an external...

    Pretty much all VFD's have inputs for external run controls or remote controls, the first 2 or 3 inputs are often used for the run commands typically what are known as 2 wire control which work on...

    Based on what has been said, if you run both motors at 25 Hz then braking times should be similar, since you are looking at the same slope over time and same starting point. DC injection is usually...

    Change your gearing so the motor runs at 15-30Hz for threading, this will decrease the rotational inertia. Newer VFD's can give a bit better motor control and smoothness when you do the autotune, and...

    Encoder on a manual lathe is a bit of overkill (tried it, and little benefit at this level), unless you plan to go to CNC, you are looking at a 1-2K additional expensive for encoder and accompanying...

    The TEFC I usually run from 15-120 Hz, below 15 Hz you could run into some cooling issues in theory, but you are not running the motor anywhere near full load for any length of time. Since the...

    If you are running a 1340 or 1440 lathe and can fit a smaller motor pulley, then I would also consider a 3 Hp vector motor and run it to 120 Hz with a 240VAC VFD. I just worked with another person...

    Wouldn't use a 2 pole motor on a lathe, you are correct that a 4 pole is more ideal for a most manual lathes that top out at 2500 RPM. You also have smoother pulses and less visible surface issues. A...
