I recently rewound a Hextronik 1300Kv brushless motor (HXM2730-1300), also called “blue wonder”. I rewound it to see if i can make it better. Better thrust, cleaner windings and lower current consumption.
Some specs related to the motor insides…
- Number of stator poles : 12
- Number of Magnet poles: 16
- Motor tube diameter : 8mm
- Gauge of wire : 26AWG (0.43mm diameter)
- Number of turns per stator tooth : 14~15
- Termination : WYE
This motor is a 12N16P motor wound in the ABCABCABC format with a WYE termination. My goal here is just to rewind the motor with a better wire in a cleaner manner. No other modifications done.
A really good link for rewinding is from RcGroups : Link
The stator after the rewind. Not pretty.
Rather than terminating the wires loose, i decided to terminate them at a solder board. The rubber grommet is just to provide some clearance between the winding and the board.
Soldered stator. The black thing you see is the dried ‘liquid tape’. Not needed actually.
Finished motor with the new termination board.
