with the unit allowed the auger to spin at a minimum of 5
about 10 Hz.  
In other words, the customer was running the equipment as
itself based on inefficient motor usage.  

Proposed solution:  
WSC was able to determine that the customers target auger
rate was between 1 and 4 rpm.  The most practical way to
achieve the target was to change the drive and idle gearing
We replaced the drive sprocket  with a smaller sprocket.
We replaced the idle sprocket with a larger sprocket.  
Result:
The customer now has an operating range of 0 to 4.75rpm.

Benefits:  
The motor operates inside of its intended speed range.
The VFD operates closer to its intendended speed range.  
The customer has better adjustability inside of his intended
production range.  
Power Transmission
Benefits:  
The motor operates inside of its intended speed range.
The VFD operates inside of its intended speed range.  
The customer has better adjustibility inside of his intended
production range.  
Before:
auger turns too fast; speed range is not optimized for the customer.  
During:
Determine what sprockets are needed to hit the customers production range.  
re-design gear enclosure, generate a cad model.
After:
We have hit the customers required production range of 1 to 4.75 RPM.
