1. A linear motor control system comprising:
- a linear stage, comprising a first mobile magnetic component and a second mobile magnetic component;
a first stationary magnetic component that magnetically engages the first mobile magnetic component;
a second stationary magnetic component that magnetically engages the second mobile magnetic component;
a first controller to activate a first magnetic displacement between the first stationary magnetic component and the first mobile magnetic component when the linear stage is in a first range of positions; and
a second controller to activate a second magnetic displacement between the second stationary magnetic component and the second mobile magnetic component when the linear stage is in a second range of positions.

Abstract
A system, method and apparatus for controlling a linear stage a pallet is described herein. In one aspect, a conveyor system includes a conveyor pallet that includes a first mobile magnetic component and a second mobile magnetic component. A first stationary magnetic component can magnetically engage the first mobile magnetic component. A second stationary magnetic component can magnetically engage the second mobile magnetic component. A first controller can activate a first magnetic displacement between the first stationary magnetic component and the first mobile magnetic component when the conveyor pallet is in a first range of positions. A second controller can activate a second magnetic displacement between the second stationary magnetic component and the second mobile magnetic component when the conveyor pallet is in a second range of positions.
