Hello all,
So, how much load has anyone successfully placed on a micromotor?
I used a micromotor to steer 2 tandem axles in one of my model of a
sideloading container truck (see olivierg.50megs.com/steering.htm for
details). When the truck was loaded, the micromotor slipped (at the grey
fitting over the black output shaft). When the truck was moving, however,
the steering was fine.
My current model is adding a countersteered rear axle, and this seems to be
too much for the micromotor, no matter what.
Anybody has any advice on how to reduce slipping?
Anybody has any pictures or explanation of models using micromotor (for
heavy loads)?
Thank you,
Olivier

| I have not used the micromotors for any steering assemblies but the geared motors work very well. Using short, low power (and counted so to get back to center easily) pulses I've had no problems either moving or stationary. Getting them to fit into (...)

| I used them on my Silver 8458. They will slip and stall when the truck is not moving. Too much torque required. (URL) Fay rfay@we.mediaone.net (URL) <ogerou@hotmail.com> wrote in message news:GB16o4.4G1@lugnet.com... (...) be (...) (24 years ago, 31-Mar-01, to lugnet.technic)

| (...) I had a setup like this on my mobile crane which worked pretty well - it would steer when the vehicle was stationary, but was fairly slow, although not slow enough to attract adverse comments from non-lego "operators". You can see some details (...) (24 years ago, 2-Apr-01, to lugnet.technic)
