Theory of Operation
The QuickStick HT is a new approach to linear synchronous motor (LSM) technology, which
provides a faster, cleaner, and more advanced alternative to conventional propulsion and con-
veyor methods. With a scalable, adaptable, and innovative design, the QSHT transport system
can achieve various acceleration and velocity profiles while moving a wide range of payloads
with high precision.
The QuickStick HT motors are similar in operation to a brushless DC rotary motor, with its
stator (motor primary) and rotor or armature (motor secondary) ‘unrolled’ to allow linear
motion as shown in
. The motor primary is a series of coils that generate a magnetic
field within the QuickStick HT motor. The motor secondary is an array of magnets that is
attached to the object to move, referred to as a vehicle. The motor primary generates a mag-
netic field to move the motor secondary (vehicle) in a controlled manner. The QSHT motors
also use the magnets on the vehicle to track the position of the vehicle over the motor.

QuickStick HT Transport System Advantages
An advantage of the QuickStick HT transport system is that the motor secondary (vehicle) is
not connected or tethered to the motor primary. This configuration allows the vehicle to travel
further and faster than connection cables allow. Another advantage is unlimited travel length.
The result is a propulsion solution with excellent reliability that is efficient, quiet, and clean.
