摘要： Dynamo electric machines and stators for use in such machines are provided. The stators comprise plates configured to be substantially flat and a plurality of spaced apart projections or teeth extending away from the plate and, together with the plate defining a plurality of slots therebetween. The stators comprise masses of metal particles. Using stators made from such metal particles provides enhanced machine efficiency, which is believed to be because of reduced eddy current effects in the stator. Motors including rotors having generally flat arrays of permanent magnetic poles and such stators which are spaced apart from and generally facing the permanent magnetic poles and have a plurality of magnetic windings, and pumps powered by such motors are included within the scope of the present invention.

摘要翻译：提供用于这种机器的发电机电机和定子。定子包括构造成基本上平坦的板和远离板延伸的多个间隔开的突起或齿，并且与板在其间限定多个槽。定子包括大量的金属颗粒。使用由这种金属颗粒制成的定子提高了机器效率，这被认为是由于定子中的涡流效应降低。包括具有大致平坦的永久磁极阵列的转子和与这些永久磁极间隔开并且大致面对永磁体并具有多个磁性绕组的转子和由这种电动机供电的泵的电动机包括在本发明的范围内。
