DC double-tacho-generator with permanent and separate excitation
Types TDP 1,2 + TDF 1,2
This is single-shaft machine comprising a permanent magnet tacho-generator and a separately
excited tacho-generator. The speed-proportional voltage of the permanent magnet machine is used to
excite the separately excited generator. As a consequence, the output voltage of the separately
excited tacho-generator changes with the speed according to a quadratic function. The voltage
characteristics are depicted in the diagrams below.
