Before designing a QuickStick HT transport system, review the following information:
• Application for the QuickStick HT system.
• Desired throughput.
• Maximum payload.
• Total transport length.
• Transport topography.
• Move time.
• Vehicle length.
Once these characteristics are known, identify additional requirements:
• Accommodations for vehicles less than 0.5 meters [19.7 inches] in length.
• Accommodations for track length and topology.
• See Figure 4-1 on page 124 through Figure 4-7 on page 130 for QSHT motor
and motor drive mechanical drawings.
• See Figure 4-8 on page 131 for the QSHT magnet array mechanical drawing.
• Perform the calculations as shown in Determining Thrust Force on page 321 to deter-
mine the optimal thrust force, Vehicle Gap, and magnet array size.
• The QuickStick HT transport system allows only one vehicle at a time on a motor
block (see
Table 3-2 ). Each block is a discrete motor primary section of multiple coils
within the motor that is energized over its whole length.
• The magnetic attractive force present per magnet cycle and the required thrust must be
accounted for with the QuickStick HT motors (see
Table 3-3 ). Complete tables for
thrust and attractive force are available in Data for Transport System Design Calcula-
tions on page 317 .
