It sounds like a weak field (low current) rather than no field.  My memory 
may be playing tricks on me - but IIRC, with no field, my E15's ammeter 
pegs 
and the motor barely moves.  It doesn't overspeed because it can't get 
going 
at all with no field.  

But perhaps yours is different.

I might next try getting out the ammeter, and measuring the actual current 
the field is using.
