摘要 |
Embodiments of the present invention may include a method of producing mechanical power by moving a coil (134a) coupled to a shaft (132) partially into a magnetic cylinder (114) having a magnetic end cap (122) containing a plurality of stacked magnetic forces, changing the magnetic polarity of the shaft, moving the coil (134a) out of the magnetic cylinder (114). In other embodiments, there is an electric motor apparatus comprising a magnetic cylinder, a coil coupled to a shaft, and a means for reversing the magnetic polarity of the shaft. |
