Re: (ET) Dead sweeper motor, need new one

You may have a short in the armature or a ground to cause that extreme
current.  These motors are "random wound" using standard enamel wire and
any competent local motor shop should be able to take the data from it
and rewind it.  Ask for a quote first as the price may be high.  I'd
estimate 8-10 hours.  A "mom & pop shop" may be willing to do it for
fixed price but expect $200+ for winding and overhaul.

          What manner of long thin motor? Like the early mower deck
motors? 
Or like the permanent magnet traction motors, of which there are three
types that I am aware of ?
