From information on the Internet I understood several things:
Low KV motors are better for gimbals. For lower KV thinner wire is used with more turns.
Outrunner motors have more torque than inrunners.
More poles give smooter rotation and finer resolution.
PMSM motors are driven by sinusoidal signal and therefore are rotating smoother than BLDC.
Please correct me if I am wrong.
So, now, this is a medium sized (60mm OD) motor from a gimbal which has very high torque. The wire is thick, its inrunner, has low pole count. All these things oppose the information above. What is going on here?
