Tachogenerators Germanischer Lloyd NORIS A.C. tachogenerators are maintenance-free speed-measuring devices using permanent-magnet excitation. They are designed to provide an A.C. voltage signal that is proportional to a speed of their drive shaft. It is possible to use either voltage or frequency as the measured variable. Tachogenerators are used where a direct supply is desired for indicating instruments, monitoring or processing devices. Drive is either direct from the take-off shaft by means of couplings or indirectly via belt-and-pulley or friction wheel arrangements. Tacho-generators are working without operating voltage. General notes on Type GE14-.. Method of operating of GE14-.. tachogenerator The drive shaft rotates a permanent magnet in a stationary conductor and induces a voltage in the latter whose amount and frequency are proportional to the speed of the drive shaft. The GE14-.. is of 12 the pole type having 6 pairs of poles so that the frequency of the alternating voltage is 1/10 of the input speed. Details of the GE14-.. tachogenerator • There are four standard variants available of this series: • GE14-09 with connection 8 to DIN 5377 and quick-connect terminal • GE14-091 with connection 8 to DIN 5377 and connecting cable • GE14-10 with connection 2 to DIN 5377 and quick-connect terminal • GE14-12 with skewing shaft with lug and quick-connect terminal • Output is a sinusoidal A.C. voltage • Long life through sturdy suspension of drive shaft (GE-14-10) • Direct drive possible via flexible couplings (GE14-10) • Indirect drive possible via V-belt pulleys or friction wheels (GE14-10 • Wheels or pulleys can be mounted directly on the shaft (GE14-10) Voltage characteristic The voltage characteristic shows the output voltage plotted against speed at a load of 1 mA: Load Characteristic The load characteristic shows the drop in output voltage in % at varying loads and at different speeds: Voltage drop
