Abstract
A rotary encoder for determining the rotation of an object to be measured includes a shaft that is coupled to the rotation of the object to be measured, as well as at least one bearing in which the shaft is rotationally mounted. The rotary encoder also has a rotary-transducer base member having a bearing fixation region at which the bearing is fixed in position, at least one depression area being formed continuously with a defined depth on the rotary-transducer base member along the periphery of the bearing fixation region such that it surrounds at least half the periphery of the bearing fixation region.
