Hi,
I went through a lot of postings concerning PWM (Pulse Width Modulation) in this
newsgroup. My conclusion is that it is possible.
However, I haven't seen any description of the longterm (after) effects of PWM
on the motor itself.
So I have a few more questions:
- Is there an "official" statement from TLG (or Jake) that the motor can handle
PWM?
- What is the ideal frequency? I read some books about model rail roads where it
is stated that the frequency must be between 50-100Hz.
- Did someone exchange the motor for another brand motor (Faulhaber or so...)
I want to experiment with pure PWM (no RCX or DCC) and to make use of a block
controled layout. For me this will be a challenge in both ways: lego wise and
electronics.....

| Guido- I wouldn't get too concerned with the "long term" affects of PWM on LEGO train motors for a variety of reasons: 1. TLC already uses PWM in the RCXs 2. LEGO train motors don't last all that long anyway (we kill a lot of them running trains 5 (...) (20 years ago, 21-Jul-04, to lugnet.trains, FTX)

| (...) I've been running Mark Reiley's LDCC on omy layout at home and at rtlToronto train shows--my 9v train motors seem to still be just fine. I occasionally take 'em apart and clean the contacts and such, and put a squirt of graphite on the various (...) (20 years ago, 21-Jul-04, to lugnet.trains)
