Abstract
An electromechanical motor and method for operating same result in a motor low-wear, quiet, slip-free and simple structure, wherein the drive shaft is driven free of bending moments, can be arrested in quiescent position and can be operated at low speed. A drive ring is disposed for line contact with the shaft and moved by a combination of linear displacements of respective electromechanical drive elements to execute a circulatory motion.
Claims11
An electromechanical motor comprising:
- two electromechanical drive elements respectively producing linear displacements;
- a non-deformable drive ring;
- rigid, non-articulated mechanical connections respectively connecting said drive elements to said drive ring for causing said drive ring to execute a circulatory displacement motion by a combination of said linear displacements with no deformation of said drive ring;
- and
- a shaft in rolling line contact with said drive ring, said shaft being rotated by said circulatory displacement motion of said drive ring.
