Are you familiar with NEMA minimum diameters?  NEMA stands for National Electrical Manufacturers Association, and they are the organization that sets standards for electric motors.  The particular standard that is important to your belt drive is the minimum sheave/sprocket diameter standard.  These minimums are important to keep from causing shaft or bearing damage to your electric motor.  You can find this information in our Preventive Maintenance and Safety Manual.
