Q: What is the difference between a Full Rate Motor and an Up Rate Motor? 

A: Your motor label will have two very important pieces of information Horsepower (HP) & Service Factor (SF). There is one simple calculation which tells the whole story of Full Rate Motors Vs. Uprate Motors...

HP X SF = Total Horsepower

When you are ordering a replacement motor do the calculation above to make sure the Total HP of your current motor matches the Total HP of the new replacement motor.
