Shaper Motor Sizes

What is the horse power required for a shaper? They were once line shaft machines with lots of torque. Now almost every one has its own dedicated electric motor. The best answer would be some actual examples. Shaper manufacturers recommended and often shipped their machines with electric motors of the horse power rating in the following table:

5" Perfecto 1/4 hp.
7" Perfecto 1/3 hp.
7" Atlas 1/3 to 1/2 hp.
7" Ammco/Rockwell/Delta 1/3 hp.
7" Rhodes 1/2 hp.
7" Southbend 1/3 to 1/2 hp.
8" Shape-Rite 3/4 hp.
8" Logan 1/3, 1/2, or 3/4 hp.
15 Hendey 1 to 1.5 hp.
20" Hendey 2 hp.
