In augmented linear drive motors with large current, the tail section requires a pair of bridging conductors to connect the main rail and the augmented rail. In previous experiments, to ensure uniform magnetic field conditions during armature acceleration, the armature’s starting position was typically placed ahead of the tail bridging conductors (along the direction of motion) to avoid magnetic field abruptions that could affect acceleration and motion stability. This paper investigates the relative positional relationship between the armature’s starting position and the tail bridging conductors. The electromagnetic driving force on the armature at different positions is calculated, and its influencing factors are analyzed. The feasibility and risks of placing the armature’s starting position inside the tail bridging conductors are explored. The findings can guide the determination of the armature’s starting position and the optimized design of tail bridging conductors in augmented large-current linear drive motors.
