Motor Timing

Hey, I was just playing around with an armature out of a tamiya black motor the other day.
I put it in a modified can, and cranked the timing all the way up.
Needless to say, the RPM rose, but the torque dropped off.

When is too much timing too much?

By the way, it was balistically fast... But it generated a lot of heat... and run time was down. (From 20mins to 12.5mins)
I also set it at standard, and also, the "most efficient" possition.
Both of those were slower, hence not as fun.

Do any of you guys play with very advanced timing???
How about any of you guys with dyno's, what is their diagnosis?

If motor efficiency doesn't matter to you, too much timing is the moment the motor ends up slower around the track.

Large amounts of timing cause a lot of brush and comm wear.

Most people will set their motors for good efficiency, with maybe a little extra advance for more power.

Thumbs up

Thanks, that's the sort of info I was interested in...

I do race my car's, but I play with them more... I just picked up a couple of Tamiya black motor arms (The brushes let go in the original can) so now I use those for "playing", and experimenting with my mod. cans...

I have found that approx. 25 degrees timing is the 'most' efficient, while 55 degrees is the highest reving...

By the way, does anyone know how many turns are on the black motor?
