DUALSKY XM9015GB-SR, slip ring edition Motor (without slip ring)

The Dualsky XM9015GB-SR is a brushless outrunner with a 90mm stator diameter and a 15mm stack.

The XM number encodes the stator: 90mm is the stator diameter and 15mm the stack length, so the code tells you the physical size of the motor rather than a marketing class.

Slip ring edition: this version supports a slip ring, which allows a rotating assembly such as a gimbal or a retractable mechanism to carry power and signal through a continuous rotation. Note the listing states the motor is supplied without the slip ring itself.
