2 coils per slot. 1 coil per comm bar. 25 slots * 2 coils/slot = 50 coils. Minus one dead (unconnected) coil = 49 coils for 49 comm bars. Dead coil keeps spacing and balance. Odd number of comm bars needed for 4 pole wave armature winding.Major,
how do you have an armature design that has a different number of Commutator bars and a different number of armature slots?
How does this work?
Some pros and cons for each way. Existing tooling plays a big part in the choice. For high volume production, equal bars and slots are probably best, for both design and process.what advatages does this have over the same number bars and same number slots? like 49 and 49 in the GE 11?
Hi Yab,You can see.....
Warp 11 have 25 slot in armature, but 49 bar comm.
I would like to know the difference rpm and torque of each motor at same voltage and current!..
yabert i think I see from your photos...you have the one piece brush design i was told by the people at warfeild to MAKE SURE that this was upgraded to the 2 piece brush design...this would then be like the WARP 11.
Hi Yab,Is it a big disavantage to have one big brush hold with two spring compare at 2 brush with one spring on each?
I assume the same area of brush contact (2x1 = 1x2).
