Re: (ET) Snowblower motor in E12?

When blowing heavy wet snow I have managed to pull over 350 amps from the NiCDs at 36 volts. Assuming 300 of that was the snowblower, that's 16hp peak sustained (15-45 seconds)

The snow blower motor that I had was a a monster.  I have oftened wondered 
if anyone has done this.  It is a series wound motor with some small 
windings to limit the motor speed with no load.  The small winding drew 
something like 6 amps.  I think the motor can generate 10-15 hp for short 
periods.  Being a series would would require a diferent control circuit to 
reverse the field relative to the armature.  You would not get as flat a 
speed load curve but it would have lots of power.  You might put a switch 
on the speed limiting field winding to give you speed options and increase 
the efficency on the motor if you don't need to limit the speed to 3600 
rpm.

  I notice the snow blower motor is
  rated 2.5 HP @ 66 amps/
  My E12 has original 1.5 motor with a Curtis controller.
  Would it be possible to replace the original motor with a
  compound wound blower motor?
