    Hey guys does anybody have any thoughts on treadmill motors. There seams to be quite a bit of talk from our brothers across the pond using these to convert their mills? i don't seem to find enough detail to tell me if they actually mean a treadmill (as in indoor jogging?). Anybody know anything about treadmill motors???:feedback:

    Treadmill motors are normally about 2.2KW and are either DC brushed or brushless and have a large inertia disk to increase the inertia of the motor.
    All i can think you could use it for would be the spindle but the motors are not designed to go fast, so gearing will be needed.
    also they are huge and weigh about 10-15 KG, so your mill will need to be made of something really strong, like MDF with unsupported 12mm rails :)

    lol....... i was thinking more cd drive rails. I cant seem to find anything smaller than the sort of size motor you mention. All i can say is they must have bloody big CNC machines :-)

    Unless they mean dog tread mills, i know i have seen treadmills for pets on TV, and i think the saying "only in america comes to mind" :)

    lots mention about super market conveyors as well. These can come quite small if you think about the corner spare shop???

    There are a number of people using them as servo motors with a 500 count encoder mounted on the end and driven by the Gecko or Leadshine servo drives.
    Mainly aimed at the bigger machines like the Boss 2 and 3's but you have to go 3:1 or 4:1 reduction.

    Maybe its about time someone here thought really big like the one on youtube doing the aircraft wing. Might need to rethink the new shed a bit though?
