Two Flier Slotted Commutator PMDC Motor Armature Winder Rotor Winding Machine
Application:
Armature winder for slotted type commutator armature,Vacuum cleaners hammers power tool
Hook/Tang type armature is easy to do armature winding, while armature with slotted type requires more complicated winding technology,
Why motor manufactuer use slotted commutator?
A slotted commutator motor could use less copper materials and run longer than a tang type commutator motor
Advantages:
1. Slot type armature with thin, thick wire machine can bed handled by automatic winding machine,
Machine had good feedback of winding a small 0.25mm wire diameter armature
2. Have good adaption for slot type commutator with groove,
No need to work with special designated slotting undercutting machine
3. Got good feedback in wide application from customers
4. 98% yield rate above assured when the slot commutator quality is good
5. Till now it is the best machine in China for winding slotted type armature
Feature:
| Lap winding with double flyer wire gauge range | Usually 0.20~1.2mm, Max wire machine handled 1.35mm (about AWG16) |
| Armature commutator type | Slotted type riser type not hook type |
| Automatic or semi automatic | You only need to load and unload armature, other actions such as hooking, winding, indexing and cutting are wound by machine automatcially |
Winding and welding are the two most improtant process in building motors, WIND-ST-TD2B winding
machine is mainly for automatical lap winding a slotted type commutator armature as below

Question and Answer:
Q:Wire size and Wire slot size relation (Length,width and depth)?
A: The wire slot should have enough space for the wire to stay inside Wire size 17AWG (1.15 mm),
Slot: blade width 1.143, length=7.14 mm, depth= 5.95 mm
and we think if the depth is bigger, the wire can acquire more space to stay inside slot,
while depth is more, length is more too,
Q: How to settle if there is indexing issue?
A: Could you please check if the commutator was pressed consistanctly each time at same
location according armature stack?
The push pin witness marks on the commutator are consistent.
Because armature commutator and stack position is very important for indexing consistantly
How to do pin hole test for the wound armature to verify the wound armature quality?
Operation steps for brine pinhole test for enamelled wire.
1.Prepare copper wire or wound armature samples according to the requirements
2. Connect the power supply, switch on the power, adjusting DC voltage meter adjustment knob,
the voltage value is 12V.
3. Copper wire or wound sample was immersed in 0.2% of the concentration of salt solution
(main ingredients are water, salt, pure alcohol 3%)
In the sample, the negative electrode connected with DC power supply, DC power connected with the
positive solution.
4.Within a minute, observe the change of the sample, if the sample has no obvious change, indicating
that the sample without pinhole, if the red and the penetrating phenomenon around the sample you
need to pay attention to, at this time, explain the pinhole, carefully count, there is the phenomenon of a
few, there are a few pinholes.
5.After the experiment, turn off the power and take out the sample
