Motor Types
The MagneMover LITE motor bodies are available in two styles; motors with integral rails
and railless motors (see Mechanical Specifications on page 148). Switches are only available
with integral rails. Both motor body styles perform the same and have the same operating
specifications. Rails are available in either aluminum or stainless steel.
The MagneMover LITE motors are available with two different communication options. The
motors using either communication method perform the same and have the same operating
specifications.
• RS-422 Communication – Uses RS-422 between the motors and from the motors to
the node controllers. Available with the following motor types:
• RS-422 standard (rails/no rails).
• RS-422 air-cooled (rails/no rails).
• RS-422 standard switch (rails).
• Ethernet Communication – Uses Ethernet between the motors and from the motors
to the node controllers. Ethernet communication provide the following benefits:
• Provides higher data transfer rates.
• Reduced number of node controllers.
• Increased limits on number of motors per path and/or vehicles per path.
• Foundation for enhanced condition monitoring and diagnostics.
• Ability to create additional paths without additional node controllers and
cabling.
• Available with the following motor types:
• Ethernet standard (rails/no rails).
• Ethernet air-cooled (rails/no rails).
• Ethernet standard switch (rails).
• Ethernet high payload switch (rails).
Available Thrust
Several variables determine the thrust available from the MagneMover LITE motors to move
a vehicle (puck):
• Magnet array length (in cycles). The MM LITE always uses 1-cycle arrays.
• Vehicle Gap (distance between the magnet array that is attached to the vehicle and the
motor). The vehicle gap is fixed in standard MM LITE configuration by the height of
the rails on the motors and the location of the pucks on the rails.
• Friction or drag between the vehicle and the guideway.
