Is this AC motor ok for a smallish 3DOF rig?

    Hi All,

    I've been reading a lot, and learning a massive amount on this forum so thank you to all the contributors. I'm looking to build a small 3DOF using the following motors:

    https://www.gearedmotorsuk.com/prod...0.75-kW-and-an-Output-Speed-of-35-rpm/P562047

    COuld someone tell me if I'm in the right ballpark with this motor please? One thing I've not seen mentioned is the term "Service Factor". It seems it's basically a surge capability. Does anyone take this into consideration when looking for motors or do you simply go for the nearest number to one?

    Also, still at the learning stage for VFCs, so if there is a regular go to unit, please let me know.

    Cheers

    Dave

    I don't know what context you got "Service Factor" from. but surge is a function of design for a true surge axis, and can also be simulated in SimTools using the pitch axis.

    Design plays a critical role in determine the motors needed for a given rig to move a certain mass at a given speed. While not created with a traditional 3DOF in mind SimCalc does provide an easy way to get your head around physics and design choices: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/
