Theory of Operation
The MagneMover LITE is a new approach to linear synchronous motor (LSM) technology,
which provides a faster, cleaner, and more advanced alternative to conventional propulsion
and conveyor methods. With a scalable, adaptable, and innovative design, the MM LITE
transport system can achieve various acceleration and velocity profiles while moving a wide
range of payloads with high precision.
The MagneMover LITE 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 Figure 6-1. The motor primary is a series of coils that generate a magnetic
field within the MagneMover LITE motor. The motor secondary is an array of magnets that is
attached to the object to move, referred to as a vehicle (puck). The motor primary generates a
magnetic field to move the motor secondary (vehicle) in a controlled manner. The MM LITE
motors also use the magnets on the vehicle to track the position of the vehicle over the motor.

MagneMover LITE Transport System Advantages
An advantage of the MagneMover LITE transport system is that the motor secondary (vehi-
cle) is not connected or tethered to the motor primary. Being untethered 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. The MM LITE transport system also provides high reliability because it does not
require frequent replacement of power transmission parts.
