Re: [ATM] Treadmill Motors

You could always ditch the motors altogether and actually jump on the treadmill to power the machine.  Just think of all the exercise you could get!  It may be low tech... but it would certainly be a first ;-)

  I have been toying with the idea of building my first grinding machine
  employing one or two motors.
   
  I have two family members who work for a treadmill manufacturer and they
  can get me treadmill motors at cost.  I am curious to find out if
  anybody has any experience with these and knows of any problems that I
  may encounter.
   
  Since I can get the motors from the factory I have a wide range to
  choose from.
   
  The low end motors are ~ $10 and the factory has to add a cooling fan
  and the pulley.
   
  On the high end I can get the motor from a health club machine that
  produces 3 HP and can run a treadmill up to 12 MPH (no idea on the motor
  rpm).  I can pick up one of these with the controller, transformer, and
  the pulley already attached for $75.
   
  I am leaning toward one of the higher end motors since they are intended
  for more frequent use.  Is there any disadvantage in overpowering the
  grinding machine?
