| 简介 |
This application concerns embodiments of a low cost magnetically geared lead screw (MGLS). In some embodiments, a MGLS system comprises at least an outer cylinder, an inner rotor, and a translator sandwiched between the outer cylinder and the inner rotor. In various embodiments, the MGLS overcomes some of the disadvantages of other systems by skewing magnetic pole pairs on either or both of the outer cylinder or the inner rotor instead of skewing magnetic portions of the translator. By skewing the pole pairs, the translator placed between the outer and inner cylinder is generally not required to contain any magnetic material (such as permanent magnets or magnetic rings, rare earth elements, etc.), which may otherwise cause the translator to become costly and/or heavy, or to exhibit any other number of deficiencies. |
