The X Wagon
On the Y beam the X wagon is attached, which generates the X movements.
On the X wagon there is a solder paste cassette interface and a positioning
camera.
The X wagon is powered by a cog-free brushless linear motor, designed for
unlimited stroke (travel) servo applications. It produces smooth operation
without cogging.
The linear servo motor consists of a U-formed stationary magnet track and a
moving coil assembly. The multi-pole magnet track is built up of alternating
polarity magnets bonded to a steel plate. The coil assembly must be centered
within the magnet track and guided by bearings.
