Theory of Operation
MagneMover LITE motors use the vehicle geometry, among other functions, to control the
spacing between adjacent vehicles on the track. In the current MM LITE systems, vehicle
geometry is specified only as a longitudinal length, and is applied along the centerline of the
travel path. This geometry specification provides the correct spacing for vehicles along a
straight path when the actual vehicle length is used. On curved paths, a longer length must be
used to account for the effects of the width of a vehicle, which causes extra space between
vehicles on a straight path.
This new feature simplifies the configuration of the system while allowing for more optimal
packing of pucks than the current method achieves. MagneMover LITE systems typically use
a rectangular vehicle. This new feature allows specifying the geometry of the vehicle as a set
of rectangular boundaries. These boundaries allow setting the center of the vehicle offset
from the center of the vehicle (puck or tandem puck).
When using the (potentially offset) rectangular geometry, the MagneMover LITE system
performs all necessary calculations to provide proper spacing of vehicles without collision in
both curves and straight sections of track (including straight sections near the curves). There
is no need to worry about the geometry of movement, all that is required is to specify the
rectangular geometry of the vehicle and design a compatible track geometry.
The MM LITE system does not support wide vehicle in the following situations:
• When running the MM LITE system in simulation mode, vehicles are spaced based only
on their length. The configured width of the vehicle is not used for spacing the vehicles.
• When using the Track Graphics window in the NCHost utility, vehicles are always
displayed as pucks, not at their configured size.
