Electromagnetic vibratory engine (Machine-translation by Google Translate, not legally binding)

摘要

Electromagnetic vibratory motor for rectilinear drive whose masses are coupled together elastically by means of spiral springs, characterized in that by appropriately calculating the springs with respect to the diameter of the turns and the length and conveniently calculating the moment of inertia of the vibrating mass of the vibrating motor in relation to possible axes of rotating vibration extended transversely to the direction of the principal vibration frequency for of the rotating fibrous characteristic of the freely vibrating mass becomes different from the frequency fa of the magnetic forces drive.
