DUALSKY XM9015HD-10, high voltage Motor

The Dualsky XM9015HD-10 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.

The HD suffix marks the high-voltage variant, intended for power systems running at higher cell counts where the standard winding would draw too much current.
