RPM and Belt Speed
			 
			 
			
		
		
		
			
			I checked the final shaft rpm and it is turning 120 RPM.  The motor is rated 170 at 12v, but I'm running it at 7.2v and there is a slight reduction in my pulleys.  The drive drum is 3/4" D.  My belt is 70" long and it travels four time around in one minute so that would be 23.33 feet/minute.   
 
Hope this helps, 
 
Jim
