• Keep the joints between sections of the guideway as smooth as possible to minimize
noise and wear on the wheels.
• The guideway must provide features to allow the vehicle to maintain its position on
the guideway (see
Figure 3-37 ).
Guideway and Support Materials
As with any installation, the operational environment must be considered when choosing
compatible support structure materials. Some examples of commonly used guideway structure
materials and key considerations follow:
Steel :
• Good strength properties.
• Strong and provides a stable platform for vehicle motion.
• Can be heavier than is necessary.
• Caution is required when using carbon steel (a ferromagnetic material).
• Can be more expensive than other alternatives.
Aluminum :
• Good combination of comparatively high strength and low mass.
• Less caution is required because of no magnetic attractive force.
• The area under the vehicle magnet array must be clear of aluminum as the aluminum
can create eddy currents, which create a breaking force.
• Available in various weights, thicknesses, and prices.
Motor Mounts
The QuickStick HT motors provide fixed mounting features on the bottom (see Mechanical
Specifications on page 124 ), which provides for a simple mounting scheme. The following
guidelines are provided for designing the motor mounts to interface with those mounting fea-
tures.
• Design the mounts to allow the motors to have a small amount of movement relative to
each other for adjustment of the motor to motor gap during installation.
• Design the mounts to support consistent spacing between the motors, which simplifies
the creation of the Node Controller Configuration File and provides consistent thrust.
• Design the mounts to make sure that the tops of all motors are coplanar to each other
to meet the standard thrust requirements. The tolerance requirement for motor top
coplanarity is dictated by the tolerance stack associated with the overall system guide-
way and structure design.
• Design the mounts to make sure that the motor is securely fastened and cannot move.
• Make sure that all motor mount locations are used and all bolts for the mounts are fully
secured.
