<p>An improved motor (90) broadly including a first member (30) and a second member (20) mounted for movement relative to one another. The first member has a plurality of poles (32) spaced substantially equidis-tantly. The second member has a plurality of arms (22). Each arm includes a plurality of fingers (27), a permanent magnet (29), and a coil (25). The fingers are arranged such that their distal end generally faces toward the poles on the first member. Each permanent magnet has a width that is greater than the pole spacing. Each arm is associat-ed with one of a number of phases. The fingers of the arms within a particular phase are arranged such that they simultaneously align with respective poles when the first and second members are in one position relative to one another.</p> |
