Trinity armature questions

[GeneralZod]

I recently obtained a few brushed Trinity armatures from a parts lot. I am unsure about the winds on two of them. They have markings on them that says 8-HVQ and 9-HVQ. Looking closer at the wires to the comm, I noticed two different gauges of wire that were wound to each arm.. I never seen this before and was wondering if this was a custom hand wind from the factory or possibly modified by someone else. I dont know if the markings signify 8 and 9 turns or not. Also, the 10x1 has flat wire wound around the arm and this is the first time I have seen this as well. What is the benefit of that? I have never tried to wind my own motors so I am no expert when it comes to this.

The name of the game is to get the maximum magnetic field, so flat wire provides a nice way to pack more copper with less resistance. Same goes for the two gauge wires. The thinner wire helps pack into the rotor tighter.

They look factory with the epoxy balance and threads holding the wires in place. Even though your pics are good, it's really hard to tell if the winds are double or triple, but if they are, an 8 or 9 turn is not out of the question.

I'm pretty sure HV stood for "high variance", referring to the difference in wire gauge.

Ah, thanks for the info! Punched that into search engine and found this......

Trinity also offers what's called a High-Variance (HV) Split Double wind that uses one strand of thick wire and one strand of thin. This is supposed to reduce inductance and make throttle response a little more crisp for high-traction applications like touring cars and 4WD buggies

Ahhh, the good ol' brushed days.......
