摘要： A high performance stepper motor comprises a stator having a plurality of pole positions. Each of the pole positions includes a plurality of stator elements or teeth on opposite sides of a stator-to-stator air gap with nonmagnetic material located in the spaces between the extremities of the teeth. Energization means in the form of a plurality of windings adapted to be connected to a multiphased drive source are associated with the stator means at the various pole positions respectively. Motive means comprising a rotor or a slider includes a plurality of motive elements which comprise teeth or slugs. In order to achieve low inertia and a high force-to-mass ratio, the motive means is located within and confined to the air gap of the stator. The motive elements comprise magnetic material and have extremities juxtaposed to the extremities of the stator elements on both sides of the air gap so as to establish flux paths transverse to the air gap and movement of the motive means relative to the stator means with the resulting force acting on the motive elements at both sides of the air gap. In order to further achieve low inertia and a high force-to-mass ratio of the passive means, the motive means comprises discontinuities in the magnetic material thereof including nonmagnetic material between the extremities of the motive elements so as to reduce flux leakage in the direction of movement of the passive means through the air gap while simultaneously reducing the mass of the motive means. By utilizing a passive means of this type, the energization means may be limited to one side of the air gap to achieve manufacturing economies and topological advantages while at the same time achieving high performance.

摘要： A print wheel comprising a plurality of character elements for use in a serial impact printer such as a typewriter is directly attached to a rotor of a high performance rotary stepper motor. The rotor which is characterized by a high force-to-mass ratio includes a plurality of circumferentially spaced magnetic drive elements which are integrally formed with the rotor hub which also supports the print wheel. In one embodiment, the stator of the rotary motor forms an axial air gap between an active stator portion and an inactive stator portion, and the rotor and print wheel are removably mounted in the air gap. In another embodiment, the stator of the rotary motor forms a radial air gap between the active stator portion and the inactive stator portion.

摘要： A ribbon cartridge in a movable print point printer remains stationary while the ribbon moves to and from the print point along a path of fixed length. The path length is established by a first flexible leader which extends from the cartridge to the print point and a second flexible leader which extends from the print point back to the cartridge. The cartridge includes a supply reel for storing ribbon before the ribbon advances to the movable print point and a take-up reel for storing ribbon after it returns from the movable print point. The flexible leader comprises a steel member having a transverse curvature for preventing the leaders from assuming a reverse curvature and maintaining a curvature of substantially constant radius.

摘要： A serial impact printing element is mounted on the slider of a high performance linear stepper motor. The slider moves through the stator-to-stator air gap of the linear motor stator comprising an active stator portion having windings associated therewith and a passive stator portion without windings. In order to achieve high performance of the motor, the slider is relatively short as compared with the stator, and longitudinal flux leakage through and the weight of the slider are minimized by the use of nonmagnetic discontinuities therein. The impact printing element includes a wheel having a plurality of circumferentially spaced character elements which are rotated to the printing position by means of a rotary stepper motor. Since there are no windings on the passive portion of the stator, the character elements of the wheel are able to pass in close proximity to the passive portion thereby allowing the center of gravity of the rotary motor to be low so as to achieve stability of the impact printing element during high speed operation.
摘要翻译：串联冲击印刷元件安装在高性能线性步进电机的滑块上。滑块移动通过线性电动机定子的定子与定子气隙，其包括具有与其相关联的绕组的有源定子部分和无绕组的无源定子部分。为了实现电动机的高性能，与定子相比，滑块相对较短，并且通过使用其中的非磁性不连续性，使滑块的纵向磁通泄漏和滑块的重量最小化。冲击印刷元件包括具有多个周向间隔开的字符元件的轮子，其通过旋转步进电机旋转到打印位置。由于在定子的被动部分上没有绕组，所以轮的字符元件能够靠近被动部分通过，从而允许旋转电动机的重心降低，以便实现稳定性冲击印刷元件在高速运行时。
