I did this on an 11" motor that was basically enclosed and attached a small piece of expanded metal to the exit hole to keep crap and fingers from getting in. In many ways some of the older motor were made back when meat was cheap and in fact can have better parts compared to what's found in newer motors where costs seem to play a bigger role than quality. Hard to say the exact condition of this motor from the couple pics sent but most of the lets call it ugly seems to be on the outside due to eviroment it was in.
Hope this helps.
Thanx for the input!
I have another motor here. This is a 7-1/8" diameter about 15"long. Allis Chalmers from the same source so maybe off the same lift.
Winding- COMPOUND (only two terminals to outside world)
Deg. C rise- windings 115
Insulation class - F
weight 102 lbs. (?)
This one has an exhausting blower on the output end, sucks air in through the brush service ports and pulls air through the entire motor. The cast aluminum blade does not have many fins, is a rough casting and doesn't look very effective compared to what could be done with an external blower IMO. This is also a candidate. I need to determine which one would be better suited for my car project assuming time will be spent improving whichever motor of the two I decide to use.
This one has much less commutator bars than the physically larger series wired capable motor mentioned earlier.
Am I correct in assuming that a compound wound motor will not have as much locked rotor and slow RPM torque as can be had from a series wound? Are compound wound motors suitable for EV's using a simple PWM controller and a transmission to achieve reverse motion?
Can a compound wound motor provide Regenerative Braking
with the proper controller?
I'll post pictures of this second motor shortly.
