One important factor to keep in mind about motors.
 

I just realized something while playing with the Xmod.

I was running freshly charged !C-3 batteries, and the yellow stage 2 motor. It was running EXTREMELY fast, and I loved the powersliding, drifting, and occasional flipping. I felt the motor after 10-20 minutes, and touched a thermometer end to the motor heatsink. You won't believe this, but the temperature rose faster than an Xmod. ;) It went all the way up to 115 degrees Farenheit. Now, I remembered how my Stage 2 blue motor had a LOT of torque, and eventually slowed down.

I remembered something from my science class: When magnets are heated, the particles can get mixed uop in all different directions, causing it to lose magnetic strength. I then decided that because the motor was getting stove-hot, the magnets might be affected because of the heat.

Just a quick reminder, you may want to buy new Neo magnets every now and then to keep the motor up with the torque.

Chuckster...

This is exactly why I buy my own pieces for motors and "roll my own". It is also why I am glad to be involved in this scale rather than the 1/10th scale stuff, because I care a whole lot less about burning up a $4 or $15 motor than a $50 to $75 one...

:rolleyes: Sorry, dude, but you don't need to keep buying new motors.....just keep replacing the magnets. :rolleyes:

Chuckster...

You could also get a BB can to keep things a little cooler.

what about a magnet zapper like they use for 1/10 motors?

this is a stupid ? but you think if i put the motor in the freezer or fridge it would help.

:rolleyes: putting the motor in a freezer won't put the magnetic molecules back in their postion, in fact it helps it stay in that position!

Chuckster...

maybe this is why my older sb hybrid got slow. i ran it w/o a heat sink... time for an overhaul.:D

How do you know that Neo magnets won't loose their strength when exposed to heat?

i think he meant keep some around so when the ones in ur motor get weak you can swap them.

Yeah and 50-75 is pretty good prices. Some of them are over $100 and if you get into the brushless ones, where are talking $350+.:D :eek:

actually, i fried one of my motor then i put that magnet is a different motor and it still spun pretty fast. i put new neos in the motor i fried, it wouldnt spin at all.

so what are the parts of the motor that die out?

The magnets and the brushes (like when you work on the motor and bend them).

It also may help to drill large holes (relative to the motor size) in both sides where there is no magnets. It will help with cooling for sure! It also may help if someone does a quad magnet motor because they are supposed to help the motor stay cooler longer.:)
