I've had a setback recently in my Gizmo. It crapped out about five miles from
home and had to be ICE-trailered back, but I've found the root cause. Broken
brush wire on one of the brushes, stuck brushes on two others, and I can't get
to number four without pulling the motor.
The commutator looks pretty nasty, all black, but not burned black, so maybe it
needs only a cleaning and trimming. I'm not sure what it's called when the bars
are cut back to a smooth surface, but this one needs it badly. The one brush
that came out is pitted.
I've been in contact with the D&D motor people, as this is an ES-10C sepex
motor. I was given a price for a rebuilt shunt wound motor. I'm hoping that
means it's a sepex motor. Can someone confirm this?
Is there any reason I would want a new motor (US$535) as opposed to a
"re-worked" motor (US$380) when it comes to reliability? I certainly do not
abuse my EVs and expect that this is a combination of circumstances, not
necessarily abuse, but can't rule it out either.
I'm pretty pleased to see a 3-5 day reference on the purchase, much faster than
I expected and faster than I can get a battery pack and monitoring system in
place.
Alternatively, I can ship the motor out west (FL to OR) and have Jim Husted work
his magic on it, but now shipping costs come into consideration, both
directions.
This is one of those times where I'm willing to pay to get the perceived value.
I don't know what value to put on a re-worked motor, though.
Opinions?
