| 摘要 |
A linear DC permanent magnet motor comprising a wound member having a plurality of windings wound on a slotted magnetic structure and a field member movable relative to said wound member, the field comprising permanent magnet means for developing a magnetic field and means for energizing with DC current at least some of the windings, the magnetic field of said permanent magnet means interacting with the energized windings causing said field member to move relative to said wound member. The motor also comprises support means for maintaining air gaps between the wound member and the field member.
