which appear to cancel one another out, except for very 

 small motors. The diagram can be made accurate for these 

 also, if the line of no-load losses a b is slightly inclined, being 

 drawn with a downward slope of about 30 per cent, from 

 the point K to a. This is not necessary for motors greater 

 than 5 b.h.p. output, but with smaller motors than 

 this the relatively greater no-load losses slightly affect 

 the accuracy of the diagram and render this empirical 

 correction advisable.
