Data for Transport System Design Calculations

The tables and curves (charts) in this appendix provide data to help in determining the optimal
QuickStick HT thrust force, Vehicle Gap, or magnet array size for a QuickStick HT transport
system design. The theoretical attractive force, which is based on Vehicle Gap and magnet
length is also provided. These values reflect simplified, optimal conditions to provide basic
guidance for determining the optimal value. Consult MagneMotion for precise values.
See Determining Thrust Force on page 321
attractive forces calculations.
See Magnet Arrays on page 102
To use the following force charts, choose two parameters to determine the third. All calcula-
tions are based on motors running at a 25% duty cycle (thrust must be limited at 100% duty
cycle to help prevent overheating of the motor).
• Determine Thrust Force – Choose a magnet array length (number of cycles) from the
X-axis and then choose the curve for the Vehicle Gap that is being maintained
throughout the transport system. Read the corresponding amount of force (thrust) from
the Y-axis or the table. See
tion about calculating the thrust force.
• Determine Vehicle Gap – From the figures, choose the force (thrust) to maintain from
the Y-axis, and then choose a magnet array length from the X-axis. Determine which
Vehicle Gap curves come closest to the intersection point. As Vehicle Gap increases,
the magnetic attractive force decreases. See
Flux Magnet Array, on page 320
• Determine Magnet Array Length – Choose the force (thrust) to maintain from the
Y-axis and then choose the curve for the Vehicle Gap that is being maintained through-
out the transport system. Read the corresponding magnet array length (cycles) from
the X-axis.
