Re: [TowerTalk] Recommendations for an electric foldover winch

Rick:

The motor shaft is 1/2 inch diameter.  You mistook the size of the keyway for 
the shaft size.  The motor develops 1/9 HP which when geared down from it's 
approximate motor speed of 1600 rpm to the 10 rpm out of the gearbox easily 
develops the 500 inch-pounds of torque.  It's a very hefty motor and gearbox. 
 Nominal current draw by the nameplate is 3.6 amps.  I put my clamp-on ammeter 
on it while raising the tower and it drew just 3.0 amps.  So the motor is not 
overtaxed.
