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.
