Tandem axes

An tandem axis consists in two axes coupled mechanically making up
a rack-and-pinion system and driven by two different motors. It is
normally used to move the axes on large machines.

There are two aspects to point out in this type of configuration:

•

A tandem axis permits using the necessary torque to move an axis
when a single motor is not capable of providing enough torque to
do it.

•

Applying a pre-load torque between the main motor and the slave
motor reduces the backlash of the rack-and-pinion system.

One of the many applications for the control of a tandem axis has to
do with gantry machines.

(A)

Main or master motor. Besides generating torque is the one in 
charge of positioning.

(B)

Slave motor. It only provides torque.

Example diagram of a gantry machine with two axes in tandem.
