ABSTRACT The invention relates to a tachogenerator of compact con- struction with a hollow shaft connection and a clamping element for fixing said tachogenerator on a rotating drive shaft. The stator of the tachogenerator is connected to a stationary machine part in order to be secured against distortion. Said hollow shaft connection is part of the rotor and is arranged on the drive shaft so as to be fixed against rotation. The stator is mounted on said rotor, which bears the coding disk, via bearings so as to be freely rotatable, whereby the rear face of the rotor is brought in plane contact with a shaft collar of the rotat- ing drive shaft by the clamping element. Placing the hollow shaft connection into the bore of the tachogenerator and mounting said tachogenerator directly on the drive shaft results in a reliable and maintenance-free arrangement, which excludes any reverse play, and in an extremely com- pact construction of the drive.
