Heat test of experimental brush carrier for an Agni motor

This video is of the heat test of my experimental brush carrier for the Agni, to compare and contrast it against the original Bakelite brush carrier material... The old carrier material fails pretty much as soon as the Butane gas torch hits it, the new carrier, doesn't mind that kind heat at all, and would keep on going.....

The finished experimental carrier, populated with the PMG 132 brushes.

Looks good, I'm assuming that apart from higher heat tolerance they also transfer the heat faster?

Yes, the tubes act as heat sinks to keep the brushes cool and because they take the current to within 2 mm of the commutator, there isn't the same reasons for them to get hot in the first place.
