Abstract
A display device has a scale in the shape of a circular arc. On an axis driving an indicator axis, a rotatably mounted gear wheel is arranged in a rotatably fixed manner, in the teeth of which the toothing of a wobble gear ring partially engages. The wobble gear ring is mounted about the axis of the rotatably mounted gear wheel such that the wobble gear ring can wobble, is acted upon by spring forces distributed around the periphery of the wobble gear ring in the direction of engagement of the toothing of the wobble gear ring in the teeth of the rotatably mounted gear wheel, and is fixedly connected to a ferromagnetic ring extending in the direction of rotation of the wobble gear ring. At least two pole shoes project through independently energizable coils to the outer circumferential surface of the ferromagnetic ring.
