[AT] Generator--doing funny things

Fri Jun 16 15:19:51 PDT 2006

The RPMs for a generator will usually be either 3600 or 1800. A 2-pole  
generator operates at 3600 RPMs, while a 4-pole generator will run at 1800  RPMs. 
There is the possibility of a 6-pole unit in which case the RPMs would be  
1200. These RPM numbers are governed by the laws of physics and also  represent 
the nominal speeds that a electric motors will run at. The actual  operating 
speeds for motors are slightly less due to slip. Electric motors  typically run 
at 3450, 1725, and 1150 RPMs based on their design and  construction.

I just retired from electrical engineering 2 weeks ago and now I have  a 
number of tractors that are begging for my full-time attention.
