Abstract: A transducer contains a rotor, on which permanent magnets are arranged in a concentrically radiant manner, and two stators are provided at both sides of the rotor. The stators are produced from a soft-magnetic material. Each stator contains a first stator section with radially outer supporting bars for first magnetic active faces of the stator being opposite the rotor and a second stator section with radial inner supporting bars for second magnetic active faces of the stators being opposite the rotor. An annular winding groove for receiving a winding is provided between the stator sections. Supporting bars are each arranged in an annular manner and each extend parallel to the rotor axis in the direction of the rotor. The magnetic active faces of the stators are end faces of projections which are uniformly spaced to one another and which protrude from the supporting bars in the direction of the rotor.

Abstract translation: 换能器包含转子，永磁体以同心辐射的方式布置在其上，并且两个定子设置在转子的两侧。 定子由软磁材料制成。 每个定子包含具有径向外部支撑杆的第一定子部分，用于与转子相对的定子的第一磁性有效面和具有径向内部支撑杆的第二定子部分，定子的第二磁性有效面与转子相对。 在定子部分之间设置有用于接收绕组的环形卷绕槽。 支撑杆各自以环形方式布置，并且每个在转子的方向上平行于转子轴线延伸。 定子的磁性活性面是突起的端面，它们彼此均匀间隔开，并且从支撑杆向转子的方向突出。
