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
Wound slotted commutator Straight stack armature and Skew
lamiantion rotor by armature winder
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
