摘要
High force and low noise linear fine-tooth motors are described herein. Such motors can include armatures having fine teeth separated by narrow slots such that a ratio of a pitch between teeth and a pitch between permanent magnet poles is less than that of a conventional iron-core linear motor. In one embodiment, such a linear motor can include a first component having an armature including a plurality of iron cores surrounded by coil windings, and a second component having a plurality of permanent magnets with alternating polarity. The plurality of iron cores can be spaced apart from one another by an iron core pitch distance and the plurality of permanent magnets can be spaced apart from one another by a permanent magnet pole pitch distance, and a ratio of the iron core pitch to the magnetic pole pitch can be less than 1.33.
