Winding Tool

Here is a tool I made to hold the stator when re-winding micro-sized brushless outrunner motors like the HP series (HP08, HP08-2, HP06, HP07). Materials used is a M5 threaded rod, M5 nut, and two pieces of a brass tube (5mmx6mm). The handle is from an old paint roll.

I rewound the HP08-2 with a winding scheme originally posted by Terry74 (thanks Jay!). Its 2 strands of 30 AWG (0.255mm) magnet wire, 5 turns, delta. Lots of detailed information on winding schemes and diy brushless motors can be found at the great website powercroco.de. Very good magnet wire can be found at Brocotts UK (search eBay).

For the record: Original winding of my HP08-2 bought from WOW Hobbies was 3 strands of appr. 0.2mm, 5 turns delta.
