    • An electrorheological crystalline mass of a molecule is formed by dispersing the molecule in a dispersion fluid and subjecting the molecule dispersion to a uniform electrical field for a period of time during which time an electrorheological crystalline mass is formed. Molecules that may be used to form an electrorheological crystalline mass include any organic or inorganic molecule which has a permanent dipole and/or which is capable of becoming an induced dipole in the presence of an electric field. The molecules used to form the electrorheological crystalline mass are preferably macromolecules, such as biomolecules, such as proteins, nucleic acids, carbohydrates, lipoproteins and viruses.Molecules are crystallized by a method in which an electric field is maintained for a period of time after the electrorheological crystalline mass has formed during which time at least some of the molecules making up the electrorheological crystalline mass form a crystal lattice.The three dimensional structure of a molecule is determined by a method in which an electrorheological crystalline mass of the molecule is formed, an x-ray diffraction pattern of the electrorheological crystalline mass is obtained and the three dimensional structure of the molecule is calculated from the x-ray diffraction pattern.
    • 分子的电流变结晶质量是通过将分子分散在分散液中形成的,并使分子分散体在均匀的电场中持续一段时间,在此期间形成电流变结晶团块。 可用于形成电流变结晶物质的分子包括具有永久偶极子和/或能够在电场存在下成为诱导偶极子的任何有机或无机分子。 用于形成电流变结晶团的分子优选为大分子,例如生物分子,如蛋白质,核酸,碳水化合物,脂蛋白和病毒。 通过在形成电流变结晶物质之后电场保持一段时间的方法使分子结晶,在该时间期间,构成电流变结晶质量的至少一些分子形成晶格。 分子的三维结构通过形成分子的电流变结晶质量的方法确定,获得电流变结晶团的x射线衍射图,并且从x计算分子的三维结构 射线衍射图。

    • A brushless direct current electric machine, comprising a stator with a hub and first stator pole teeth, which extend radially outward from this hub and have excitation coils, and with second stator pole teeth, which do not have excitation coils, interposed the first stator pole teeth, and has a rotor equipped with permanent magnets, which can rotate around the stator. The electric machine also has a base plate in which a rotor shaft bearing is inserted directly into the hub of the stator which fastens each of the second stator teeth to the base plate. The base plate is made of sheet metal and has supporting nipples oriented toward the second stator pole teeth. The second stator pole teeth have holes through which screws extend, which are screwed into the supporting nipples. The electric machine operates as a brushless direct current motor and is manufactured inexpensively.
    • 一种无刷直流电机,包括具有毂的定子和从该毂径向向外延伸并具有励磁线圈的第一定子极齿,以及具有不具有励磁线圈的第二定子极齿,插入第一定子极 齿,并且具有配备有可绕定子旋转的永磁体的转子。 电机还具有基板,其中转子轴承直接插入定子的毂中,将每个第二定子齿紧固到基板。 基板由金属板制成,并具有朝向第二定子极齿定位的支撑接头。 第二定子极齿具有螺钉延伸的孔,螺钉拧入支撑接头中。 电机作为无刷直流电动机工作,成本低廉。
