ABSTRACT:
A linear induction motor includes one ferromagnetic member thereof which is movably resiliently mounted in the motor frame so as to move toward the stator in the motor whenever current is applied thereto. A portion of the armature in the motor extends between the resiliently movable member and the motor frame. When the motor is energized the armature is free to move between the ferromagnetic member and stator. When the motor is de-energized, the resiliently movable member is biased toward the motor frame and sandwiches the armature between the member and the frame so as to prevent the movement thereof. Reactivating the motor then attracts the movable member toward the stator and frees the armature.
