Motor Collection - Old School Horsepower

[dinglem]

As pointed out above there are so many variables to consider. There are rev and torque differences between singles, doubles and triples etc... but different builders used to hand-wind their armatures with different gauge wires for example... I have a selection of team MG motors which are mainly 11 singles, doubles and triples but all have the wire gauge written on the outside, ranging from 1.18mm, 1.25mm and up to a whopping 1.32mm. Each was built for specific circumstances or track layouts etc....

The general guide is the lower the inductance for a specific wind, the more optimized it is, but as mentioned, so many variables.

And then there are different cans, magnets, airgap (which effects a lot), brush compound, serrated, cutted, timing advance ...

Returning to the Checkpoint topic for a moment... here is a bit of a project motor I picked up for a steal a while back. I assumed with it being alloy I would be able to clean it up although I haven't tackled it yet. Probably one of my next mini-projects. The original label looks fine - just really the endbell to dismantle and try to polish up a little (whilst trying to retain the 14 Turn etching), new brushes and springs. Will be interesting to see how it turns out.

Here are a few I have had for years. A couple of Kyosho Mega Clod motors, a JR's Choice, Trinity Monster Horsepower, Twisters red label that are not pictured.

I won't have the motor in hand for a week or so, but am curious if multiple companies used the blue end cap on closed endbell motors. These older old motors are unfamiliar territory for me.

Blue, white, and black were common colors for Igarashi endbells. Color isn't really an indicator of who (Reedy. Bolink, Trinity, etc.) might have sold the motor. Reedys were typically blue, but there were MRP, Bolink, and Parma blue cans too.

Yup, he nailed it down!..Definitely tru vintage MRP had blue endbells

A couple of my older motors from my stash. These two were from before I got stared in the hobby, but I'm a sucker for anything Reedy or Yokomo based.









This has to be the hardest running stock motor I have ever seen.

A few of the cleaner ones from my not as old collection.

This TC1 has to be the rarest for me because in 8 yrs. of hunting ebay I've only come across this one. No clue on turns but looks to be double possibly triple wind. Need to find a plastic case for it.








My favorite off road motor is the Sonic 2. Even though it's not the exact setup like I used to race with this one was clean and priced right.

These just arrived today.... an original and unused Checkpoint slot armature, an MG one (never come across an MG slot armature before), and a bag of bits and bobs... notable for the slot brush gear hoods and brushes, plus a pair of round heatsinks which are actually designed to be pushed on to the tiny bit of armature shaft which sticks up through the bearing at the endbell end of the motor.

Note the crossed wraps on the Checkpoint one.

Great find.
Label seems similar but mine says 23T 16T).

Just found the product photo for the very special MIH motor I posted before.
The ad said 30 gramms less weight than an usual Igarashi Modified motor.

Just cleaned this one up, added new bearings and brushes, but kept the gold springs which seem pretty soft. It's a triple wind armature, but not certain how many turns. The armature looks identical to the armature in my Monster Horsepower 1987 World Champion Joel Magic Johnson black can motor, which is 17x3, except this one obviously has a little bit more turns. If I remember correctly one of the armatures that came with these motors was a 19x3, so I have to guess maybe that's what it is.

Rebuilt this Kyosho Le Mans 240S with new bearings, Kyosho LM7 240 springs, Trinity Speed SPEC Brush ID Shunt Dual Face brushes, and a brand new Trinity/Epic 19T single wind armature.
Motor spun 32,700 rpm, 3.25A @ 7.2 volts at 0* deg timing; and 35,400 rpm, 3.5A @ 7.2 volts at 6* deg timing.
Edit- forgot to mention it has a MCI racing repro label.
