Determining a linear drive with racks and pinions

Defining a linear drive with racks and pinions is not always easy due to the many variables. For example, the rack must be able to supply the feeding force and be accurate enough. The gearbox is an important component between the pinion and the motor and the motor itself must provide an appropriate rated and maximum torque at a given speed. Eric Megens tells more about it in this video.

Excelente, me gustaria ver eso en mini actuadores de piñón y cremalleras con motorcillo eléctrico o electrónico.

How does the pitch make a difference from one module to another?
