Hello,

Do we have some data about cogging with the AKM2G vs  AKM1G  and even better would be beside competitor's motors?

Thanks,

Johan

I would say 1.5-2.0% of Tcs is typical on AKM2G (same as AKM Gen1), max. I would expect through normal production variation would be like 2.5-3%. The exception is the AKM2G size 7 will have slightly more cogging torque than the AKM1G size 7 because of the change from 10 pole to 8 pole.

I don't know of a comparison chart including vs. the competition.
