Describe the issue or the suggestion:
There are numbers through the text that don't refer to any note. The notes should be added at the end of the text.

How would you fix the issue / which content would you add or delete?
Add this text at the end as notes:

Note (1): Most of the time, these are the values given for a raw motor. Unless you are dealing with a motoreductor, you’ll be likely to have to design a reduction as well and to take the reduction ratio into account.

Note (2): rpm stands for revolution per minute, and is not an actual unit because of the word revolution, according to the International System of Units. However it is widely used because it is clearer than radians per second unit.

Notes (3) & (4): kg.cm, kg.mm, etc.; or oz.ft, oz.in, etc. are not torque units. the real torque units are kgf.cm, gf.mm, ozf.in, ozf.ft and so on. The f stands for force: kilogram-force or ounce-force are a force measure like the Newton, whereas kilogram or ounce are a mass measure. Nevertheless you’ll be likely to see them often, but keep in mind this is a common mistake.
