Phase 3
Step (9): Remain 7-8cm long magnet wire for connection use afterward.
Use magnet wire "S3" to start to wind 13 times in clockwise direction at
tooth No. 3. Wind from the hub to the outer edge of hammerhead then
back to the hub.
Step (10): Jump to tooth No. 6 and start to winds 13 times in clockwise direction
as step (9).
Step (11): Jump to tooth No. 9 and start to wind 13 times in clockwise direction as
step (10).
Step (12): Cut the magnet wire "S3". This ending of wire will be called "E3" in the
following steps. Note: Remain 7-8cm long magnet wire for connection
use.
5. Remove the coating of magnet wires
When you finish the winding steps above, you have 6 endings of magnet wire
attached to coils. Use a shape model knife to scrape off the coating of these six
magnet wires.
Finally, it is necessary to check any short between magnet wire and stator metal
parts, and need to check any short between magnet wires, S1, S2 and S3. If you
find any short between them, please be patience to rewind them again. Please
note that your Electronic Speed Controller, Receiver and Battery can be destroyed
by part defect of windings.
6. Solder magnet wires to Delta or Wye system
Now, you can make you own decision to solder the magnet wires to either Star
(wye) or Delta system.
Star vs Delta
Star (wye) system gives more torque and uses fewer amps.
In Star system, 1.73 less turns needs to be wound to get the same power and
Kv as DELTA system does.
Delta system gives 1.73 higher power and amps draw compare to STAR
system.
In Delta system, the Kv is 1.73 higher than Star system while the Kt (Torque)
is 1.73 lower
