  • Page 19: General Technical Data, Electric Implementation

    D.C. tachometer generator TDP 1,2 General technical data, electric implementation Magnet system design The magnet system of these machines consists of two permanent block magnets, developed especially for these machines and manufactured in AINi Co alloy. The direction of magnetization is determined by the material's optimum direction of magnetization. In order to guarantee operation free of ageing problems, the permanent magnets are aged artificially until they reach optimum remanent energy density.
  • Page 20 D.C. tachometer generator TDP 1,2 Voltage The listed voltages are detailed in the technical tables for the different, available machine types. Intermediate values and special voltages are possible (optional) When values are lower than the listed voltages (<10 V) the listed power rating must be reduced to (brush voltage drop).
  • Page 21 D.C. tachometer generator TDP 1,2 Maximum speed The maximum speeds listed in the tables are restricted on the one hand by the max. permissible segment voltage and on the other hand by the permissible peripheral speed. In special cases appropriate design measures make it possible to exceed the maximum speeds listed in the tables. It is possible that the maximum speed will have to be reduced when utilizing machines with built-in shaft seals.
  • Page 22 D.C. tachometer generator TDP 1,2 Temperature coefficient Temperature compensation The temperature coefficient of the permanent magnets used is dependent on the material used and is approx. +/- 0,10% per 10 degrees K of temperature change. This value applies to a temperature range of approx.
  • Page 23 D.C. tachometer generator TDP 1,2 Attachment harmonics, arising from coupling or fitting faults, influence the generator voltage because they are superimposed on the machine harmonics. In general, two fitting faults occur: phase-angle errors and parallel misalignment. The frequency of the resulting harmonics generated corresponds to that occurring at twice a given speed (phase angle) or once that value (parallel misalignment).
  • Page 24 D.C. tachometer generator TDP 1,2 Description of the method of measurement used to determine linearity: The tacho-generator to be tested is coupled to a prime mover fitted with a flywheel and operated through a speed range of 100 to 3000 rpm. An incremental encoder (1000 pulses/rotation) is used to measure the speed digitally to one decimal place.
  • Page 25 D.C. tachometer generator TDP 1,2 Brush contact voltage Silver-graphite brushes with very low contact voltage are mainly used for D.C. tacho-generators. The total voltage drop at the sliding contact commutator is affected by peripheral speed, current density under the brushes, brush pressure, and the condition of the patina on the brush contact face. The load resistance should not be made too high.
  • Page 26 D.C. tachometer generator TDP 1,2 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.
