    • 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。
