THEMA: Adoption of V200 SBModellbau motor kit(photo)

Очень хорошо. Каково теперь качество при медленной езде?

[ Eglod told : How about quality of loco  motion at slow speeds using maxon motors ]
--------------------------------
Hello Eglod!

1) I had an equally good quality of motion  at all range of speeds with serviced or new (MiniTrix)  motors as well as  with Maxon motors.

2)The reason of motor change is  a short lifetime between servicing of MiniTrix motors.

3)Now, with Maxon motors,  i have quality as with new  MiniTrix motors, but supply current is lower.

4)Maxon motors will remain this quality for significantly more long perion with comparison of usual(Minitrix) motors.

4A) This degradation concerns only motors from V200(m62) -[3 poles] and ICE-1 [5 poles]. I serviced it(cleared collector) many times. Motor in MiniTrix E40 loco works well. I newer serviced it yet.

5) Stalling at  slow speeds can occur due to poor current pickup of loco  and havent any deal with motor quality.  This problem must be solved by springing axles,

And using USP powerpacks and decoders with "Read-Through" trchnology. (read commands through isolator)

5A) Nonuniform behaviour of  loco speed, causing by dirty collector,   having at slow speeds  will remain at high speeds.

6)Mini Trix (and other ) Motors have 2 main disadvantages:

6A) Backlash of  brushes. Low quality of brushes graphite and copper of  lameles. This backlash lead to form sharp edge of brushes  when motor is mooving at one side. And when loco is reversing their direction -  this graphite sharp edge goes between lameles,crackes, and cause short circuit.  This graphite dust between lameles can cause strong degradation of  BEMF, and, therefore, cause very ununiform motion of loco.

6B)Probably, if You moove loco only in one direcrion and newer reverse it - motor lifetime must be higher. As to me - I have all locos with reversing.

6C) Plastic spacers betweel lameles wears with slower rate and can cause loosin of contact between lameles and  brushes.

Thank you for the very interesting information.

Ok. I m glad if my information and experience  can help to somebody.
