摘要： A rotor for small motors, or generators, having circumferentially arranged segmental poles which extend over the entire axial length of the rotor can be fabricated by molding a pair of elements from particulate magnetic material of high coercivity with a binder in the shape of identical crown gears; the rotor being completed by arranging the elements on a shaft with the toothed portions facing each other in interfitting engagement. Other modifications are disclosed in which the pole pieces may be formed separately from, or integrally with, a radial pole carrier, and the pole carrier may be in the shape of a spool with the segmental pole pieces assembled thereon.

摘要： The magnet carrier assembly of an electrographic copying device is fabricated from a number of separate parts instead of being machined from a single block of metal. The assembly can consist of a tubular body which supports the magnets either on the outside, or inside, peripheral surface. The tubular body can be formed by extrusion integrally with a radial spider connected to a hub which supports the body. In another form the carrier can be built up by combining specially profiled sheet metal strips with other axially extending elements with which they are joined in a tongue-in-groove arrangement.
摘要翻译：电子照相复印装置的磁体载体组件由多个单独的部件制成，而不是由单个金属块加工而成。该组件可以由一个管状体组成，该管状体在外围或外部表面上支撑磁体。管状体可以通过与连接到支撑身体的轮毂的径向星形轮一体地挤压而形成。在另一种形式中，载体可以通过将特殊成型的金属板条与其它轴向延伸的元件结合在一起而构成，它们以舌形槽结合在一起。

摘要： This invention makes it possible to use mechanically hard magnetic materials in the formation of one, or both, of the annular press rams used in closing the mold because at least one of the rams is not permitted to enter the mold a distance sufficient to short circuit the magnetic flux flowing radially between the center ram and the outer wall of the mold.
