Vehicle Design
When designing custom vehicles for use with the MagneMover LITE the following vehicle
design guidelines and considerations should be taken into account:
• The vehicle should be longer than the magnet array to protect the array from impacts.
MagneMotion recommends a minimum of 1 mm extra length at the front and back of
the vehicle.
• The quantity and locations of suspension and guidance wheels or other suspension and
guidance features is determined by the vehicle design.
• MagneMotion recommends the use of a low friction barrier, such as UHMW material,
to prevent damage to either the magnet array or the motor in the event of contact
between the magnet array and the motor. Note that for the standard pucks and magnet
arrays this UHMW material is already provided and should not be removed.
• Up to nine (9) 62 mm vehicles (pucks) in motion per meter.
• Up to ten (10) 62 mm vehicles (pucks) in a queue per meter standard, up to twelve (12)
vehicles in queue per meter depending upon application.
• The payload, vehicle mass, and required acceleration must be within the limits of the
magnet array.
• Vehicles that carry payloads sensitive to magnetic fields should provide shielding or
separate the payload from the magnet array by 50 - 100 mm.
• When using curve motors or guideways with curves, ensure the vehicle design is able
to negotiate the curves.
Vehicle Materials
Some examples of commonly used vehicle materials and considerations:
Steel:
• Good strength properties.
• High density yields heavier vehicles.
• Caution is required when using carbon steel (a ferromagnetic material).
• 300 series stainless steel is suitable.
Aluminum:
• Good combination of comparatively high strength and low mass.
• Less caution required because of no magnetic attractive force.
• The area under the vehicle magnet array should be clear of aluminum as the aluminum
may create eddy currents which will create a breaking force.
