Transport System Design
Overview
This section describes some of the basic considerations for designing a track system for a
MagneMover LITE transport system. The track system includes the guideway, the guideway
supports, the MM LITE motors, the vehicles (pucks) with magnet arrays, and the mechanism
for mounting the motors to the guideway (see Transport System Layout on page 74 for layout
guidelines).
One advantage of the MagneMover LITE system is that it is possible to have vehicles move at
different rates of speed in the same direction, or in opposite directions without a collision. The
control software makes sure that the minimum distance between vehicles (pucks) when not
moving is 3 mm [0.12 in] (see Motor Topology on page 317).

Design Guidelines
Use standard engineering practices to reduce torque, vibration, and other stresses on the
guideway and other parts of the system. Factors specific to MagneMover LITE transport sys-
tems to consider include:
• Vehicles (pucks) are not held in place if power is removed.
• There is no magnetic attractive force between the magnet array and the MagneMover
LITE motors.
• The vehicle gap (distance between magnet array and motor, see Figure 3-25) must be
maintained throughout the system.
• Keep the downstream gap (distance between motors, see Figure 3-7) as small as possi-
ble to make sure that there is enough thrust to move the vehicle over the gap.
