Is / was there a 5 pole version of the 3 pole X04 motor.

Not from Tri-ang or Hornby, but didn't Romford produce a 5-pole
version
known as the 'Bulldog'?

John.

I bought a 5 pole x03/4 lookalike motor in a bag labelled Mashima from
a
reasonably honest trader - but where it came from and who identified
it ?
Also bought an almost complete Nu-Cast B1 kit loco which has a
decidely
X04
lookalike but is 5 pole.
Theyre totally different the B1 motor has almost identical housing to
X04
and narrow bits between wiring (yes v technical) and looks very old.
The 'mashima' one is smaller neater and has wider bits. However it is
physically much smaller so perhaps X03 ?

Would be interested to know what these are if you find any info.

Iain Rice mentions in his book on chassis construction that the
Romford
Bulldog is 5 pole as John said. He also mentions the MW005 as 5 pole
equiv
to X04.

Most of the Romfords were 7 pole.
MW005 and Airfix (1001?) were 5 pole. The armature was available
seperately for fitting to Tri-ang and Hornby motors.
I probably still have one or two somewhere.
There was also a 5 pole armature for Tri-ang motor bogies.

So who manufactured and or distributed the MW005 ?

Cheers,

As they came out in two different packages in spite of being the same
product (Airfix + MW) I'd guess that MW made them and sold them to
Airfix.
It seems unlikely that Airfix would make them and sell (some of) them to
a smaller firm to market in opposition to Airfix.
The "Slimline" or "1002" motor was intended for slot-cars but used the
same armature as those intended to replace the Tri-ang/Hornby armatures.
For a long time they were my motor of preference for loco building until
I discovered Sagamis and Machimas.
Even now they are more than adequate, although Tri-ang/Hornby locos
fitted with them could do with a better gear ratio.

Thanks, getting more interesting, so who is (was) MW. ? Donnt want to google
MW unless have to ?

Anyway to differentiate between the 5 pole X04 lookalikes ?

Cheers,
Simon


My motor box has "Airfix/MRRC" on the front.
I'm afraid you'll have to google "MW" as I have no idea - remember, GB
is a foreign country to those of us in New Zealand. ;-)

Given that X03/X04s were in production for 30-40 years with numerous
changes, and presumably produced by an outside firm for
Lines/Tri-ang/Rovex/... and that the X05 was produced by MW(?) both as a
complete motor and as an armature for the X03/X04, I don't think any
list of mechanical variations would be definative.
I used to add thrust washers/bearings to all the 5 pole motors that
passed through my hands and I often repositioned the brush holder below
the pole piece so that the motor was smaller overall and could utilize
the MW brushes.
Basically, any used X05 motor today could be anything from Zenith throug
Tri-ang to MW.
Add a new "super magnet" and you've got Adam's axe. ;-)
