To figure out the rpm, divide the rpm you want by the voltage you are planning to run and that will give you the k/v you need to order. Example 40000/11.1=3603.6 You would then look for a motor close to 3600 k/v. k/v=rpm per volt. As far as cogging, it's like the motor doesn't know if it needs to go forward or backward, and it just kind of stutters. You can go to Neumotors.com and look at the 1500 series motors for specs. I think the 1940 and Neu 1512 are close in size, but don't have any personal experience with the Lehner. Maybe someone else will chime in on this, and I'm sure my cogging definition needs a little help, but you get the gist.
