Before you proceed, here are some of the tools that
you may require to wire this motor.
1. Dowel or rod of diameter 10mm, at least 100mm in length.
(Use to tighten each winding around the pole)
2. Tin Solder
3. Hobby knife.
Wiring the motor
Step 1:
Cut 15 strands of copper
wires, approximate
length 153cm for wiring a
10 turns motor (See
Figure 1)
Step 2:
Separate into groups of 5
strands and label them A,
B, C. (See Figure 2)
Step 3:
Use a marker to label
each pole (12 poles in
total) in anti-clockwise
sequence. (See Figure 3)
Before you proceed to wind the wires,
Please see our suggested winding
sequence and table.

clockwise counter-clockwise
Step 4:
For Group A, wind wires
around pole 1 in a clockwise
direction with 10 turns, then
continue to pole 2 and wind
another 10 turns in a counter-
clockwire direction. Wind to
Pole 8 and finally Pole 7 in the
direction given in the above
Winding Sequence Table
Once completed, label the
ends with tape to indicate
Group A.
(See Figure 4)
Step 7:
Ensure each wind is tight
while not to overstretch the
wires. It is suggested to use a
piece of wooden stick to assist
winding. (See Figure 7)
Step 5:
(See Figure 5)
For Group B, continue winding
from Pole 3,4,10 and ends with
Pole 9 in the direction
according to the Winding
Sequence Table.
Step 6:
(See Figure 6)
For Group C, continue winding
from Pole 5,6,12 and ends with
Pole 11 in the direction
according to the Winding
Sequence Table.
Step 8:
After every wind over the pole,
ensure all the wires are within
the pole using a small piece of
plastic or wooden apparatus.
(See Figure 8)
Step 9:
After complete winding all 3
groups into the poles, pull
together. A-in & B-out, B-in &
C-out, C-in & A-out
Step 10:
Position group wires at a suitable
location and remove protective
coating with a hobby knife to allow
soldering at that point.
Solder the group wires in 3 sets:
1. A-in & B-out
2. B-in & C-out
3. C-in & A-out
TIP:
While you want the wire to lie in the stator neatly, there is no need to
pull the wires too tightly. Instead rotate the stator in the opposite
direction to the direction of winding.

Step 11:
Solder the wires onto exposed
copper wires and use heat
shrink sleeves provided to
protect the wires.
Step 13:
Apply thin layer of epoxy over motor
core. Then fit the motor core and
connecting wires onto the aluminum
endbell. Ensure motor core is seated
completely into endbell. (See Figure 13)
Step 12:
Clean surfaces of motor core
and internal diameter of
aluminium endbell. Trial fit the
endbell into the stator.
Step 14:
Ensure that the
wires around
poles are not
protruding
above bearings.
(See Figure 14)
Apply light
grease over
bearings before
inserting the
motor case.
Step 15:
Place helical washer and circlip
over the shaft. This is to secure
motor and shaft.
You now have a brushless
motor according to your
requirement. A Tahmazo label
is provided for you to indicate
the KV or other specifications
of the motor.
WARNING:
Take extra care when inserting the stator into the motor
shaft as the pre-installed magnet are very strong.

§
Install only undamaged and balanced propellers.
Never touch, or allow any object to come into contact with the rotating propeller.
For their safety, keep all onlooker well away when preparing your model or connecting your batteries.
Switch on your transmitter first, check the position of the throttle stick (usually at the minimum position for safety), then
connect your battery pack to the speedcontroller.
A stopped propeller could result in damage to your controller and motor.
