Kb 45xl is about the same size as an lehner 2250 just that it's no where nearly as efficient.

A 557g 80% efficient motor should heat up as much as an 280g 90% efficient motor (neu 1512) while doing the same work.

While they could sustain the same kind of load by their thermal design, the kb45 would feel much more powerful as well it is because of it's extra winding and magnet mass...

I believe that you should treat a kb45xl as a rougher neu 1512...
