Where To Find Maxon Motors After Motor Man's Passing?

[MK]

While gray plastic is pretty reliable indication of the standard (Kato clone) Atlas "scale speed" motor, I recall either Cory or Paul (from Atlas) mentioning that the newer "scale speed" motors can also have black plastic brush holder end.

I remember reading the same thing.

This one look familiar?

Yes, I bought bunch of them (and the black motors too) from that seller.  You just revealed my secret source of scale speed motors!  Just kidding. 

Remember, if you are buying it in multiple quantities, use "make offer" (with a reasonable amount, like $1.20 or 1.00) and you will likely get them for your price.

Do you have a listing URL for these?

I just sent them best offer of $2.80/ea (for 15) and they accepted it.

This appears to be the same motor from another Chinese vendor for $1.48!!  ( I also made offer on the other 10 @ $2.80 - waiting to hear back)

Just a warning for the 5-pole snobs - these are straight-wound 3-pole motors.

Did anyone else notice this monster?  low speed and i bet some seriously high torque. IMHO would be great for a tender drive @draskouasshat .

With 90+ degrees skew winding I can't imagine this motor would ever cog.

. . . and they just told me they out of stock and will refund my payment! 

Just like with motorman - get them while you can!

They accepted my offer yesterday...  No retraction yet.  The listing said they had 20 in stock.

The "tell" may be that it's a 12v-24v motor. Since N and (I think) HO generally tops out at around 12v, that's only half-speed for a 24v motor.

Those "specs" on Chinese product listings should be taken wit a grain of salt (or more like with a salt-shaker's-worth).

I saw that long-bodied motor with the big skew armature too.  It looks like it's 20 or 24mm long.  But if you've got the room, yes, I bet it's killer.

Beware those "N20" motors.  I am a 5-pole snob, but it's more than that.  Those motors are not going to perform anywhere near as smoothly and as powerfully as a similarly-sized Mashima.    I've tried all sorts of "N20" knock-off motors and they are basically Mabuchi type.  They are pretty powerful, but they won't have the low-speed performance or the power of a Mashima.

I have some of those motors coming to fix a blown out life likg GP20 .. how do you get the flywheels of the axles on the old motor?

Yes, I asked this earlier in this thread too.  I have never done this before and am concerned about bending the motor shafts when pressing them on another motor.  I was thinking something like this tool to pull them off but the flange looks to be too thick to go between the motor and back of the flywheel but maybe could be filed down and still be strong enough?

If it were me I would ream out the ID of the flywheel slightly until you could just barely push it on a little bit. Then put the motor in a freezer bag and put it in the freezer. I would put a cardboard spacer on the shaft first so you can tear it off later to gurantee a gap between the motor and flywheel. Later, heat the flywheel as hot as you can get it (butane torch?) then pull the motor out. The heated flywheel and cooled shaft should allow you to use pliers to slip the flywheel on. Letting them cool should lock them in place. You could also wick some Loctite into the joint away from the motor afterwards.

If you can't ream, I would find a drill bit that is exactly the same diameter of the measured shaft at room temp to open up the flywheel hole, preferably on a drill press.

John, much thanks for the insight. Yes, I can see this temp differential approach working.  Maybe immerse the flywheel in boiling water for a while Would work too, once off and shaft bore cleaned up.
