I had a DC9 that averaged about 400w/mile on a 165V Calb 200ah battery pack. Ran it around 2500rpm or higher on average to keep it cool. Never ran hot, no blower. Finally blew it, my fault, great motor with good torque. After replacing the armature and blowing it again, I went with the Kostov.
Decided to convert it to auto at the same time, reinstalled the alternator and connected the AC back. Now after maybe 500 miles I'm averaging 6-700 watts. If I drive it at 60-70mph for more than 5 minutes or so, it's so hot you can smell it and this one has a probably 5" squirrel cage 150CFM blower with a 3" duct on it running anytime the Soliton is energized. It also seems to have much less power than I expected going from a 9 to an 11. Totally disappointed. Lots of $$$ invested and though this would be the cats meow and final motor. It's rated at 46KW, more than the 9 rating and I'm running it probably around 30-35kw most of these trips.
I have no idea why this is happening. The wiring is per the drawing, SERIES. Checked it a few times to be sure before even starting it the first time. Unlike the DC9 this one has interpoles, also at higher RPM it uses considerably more power. I'd be over 1000 watts/mile if I ran it at the RPM I ran the 9 at! I know a larger motor is supposed to produce more power at a given amp vs a smaller motor but this one seems to be less powerful using 50% more power. It's sluggish at highway speeds, even dumping lots of amps into it.
If any of you have any thoughts on it I'd love to hear it. I feel it's not long for this world if I can't figure out why it's running so dang hot even with that blower. I've worked with electric motors since the 80's but not a motor with interpoles. Is it possible the thing would even run is the interpoles were wired backwards? It's a 6 lead motor.
Thanks in advance!
