Abstract (en)

[origin: EP1201373A2] The circuit generates a control signal (theta) when the intended deflection angle of the housing of an at least partly rotating electric hand tool is exceeded. A turn rate sensor (7) that directly measures the revolution rate is connected to a comparison element (8). The turn rate sensor is an active sensor that operates on the basis of the Coriolis force.
