PURPOSE:To enable simultaneous connection of revolutions measuring apparatuses by sticking out a detection shaft to both surfaces of a casing. CONSTITUTION:A motor B using a coupling C can be connected to one end of an encoder with a detection shaft 1 projected on both the sides facing each other of a casing 12 simultanesouly with a tachogenerator D or the like using the coupling C to the other end thereof. This can indicate revolutions accurately in a wide range together with the position, direction and the speed of rotation. |
