Abstract
A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.
