DUALSKY XM9010HD-13, high voltage Motor

A Dualsky XM-series brushless motor, the XM9010HD-13, built on a 90mm/10mm stator.

The XM number encodes the stator: 90mm is the stator diameter and 10mm 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.
