port system also provides high reliability because it does not require frequent replacement of
power transmission parts.
A summary of MagneMover LITE transport system benefits include:
• Less maintenance than conventional belt conveyors.
• No moving parts within the straight and curve motor modules.
• Passive vehicles (pucks) that do not require batteries, wires, or power.
• Bidirectional movement.
• Variable transport system layout, including curves, switches, and horizontal guide-
ways.
• Anti-collision feature.
• Automated move profiles.
• Independent vehicle movement.
Motion Control
The MagneMover LITE transport system provides an integrated transport system for material
movement along one axis. Motors are linked together in Paths that define the individual
movement routes. The Host Controller can then direct movement and positioning of the vehi-
cles (pucks) anywhere along the length of the Path. Vehicles can also be moved from one Path
to another as long as there is a connection between the Paths (either direct or through one or
more Paths) through a Node (or multiple Nodes).
The design and operation of the MagneMover LITE transport system uses a minimum of
moving parts to ensure minimal maintenance requirements. Position monitoring circuits in all
motors ensure accurate tracking and positioning of all vehicles in the transport system.
Motor Topology
Each MagneMover LITE motor is constructed as a series of blocks (refer to Table 3-2 on
page 3-10 and Figure 6-2 ). Each block is a discrete motor primary section within the motor
that is energized over its whole length. Varying the magnetic force within a block and its
neighbors causes the vehicle to move in the desired direction and provides precise positioning
of the vehicles.
The control software ensures that the minimum distance between vehicles on adjacent motor
blocks is 3 mm [0.1 in] when not moving. However, this dimension can be larger depending
upon the vehicle edge location relative to the block boundary.
NOTE: The MagneMover LITE anti-collision feature prevents two vehicles from occupying
the same motor block.
