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. The tacho voltage is also measured digitally, 
however, this is measured to three decimal places. A printer connected to both measuring devices 
prints the voltage and speed. The measurements are taken at intervals of 100 rpm. At least 20 
measured values are printed per measurement. The reference voltage at a speed of 1500 rpm is 
selected as a reference point for all voltages and associated speeds.

 

The quotient obtained from the voltage at 1500 rpm and the speed of 1500 rpm is known as the 
reference gradient. The voltages and speeds from 10 measured values respectively are 
arithmetically averaged when evaluating the gradients and the gradient formed from these averaged 
values. 

 

 

Disturbance variables relative to linearity 

Load current and armature reaction 

If it is assumed that the speed-voltage curve at no load is a straight line at a particular angle, then 
when load is applied (without taking account of armature reaction) the result is a straight line at a 
less steep angle. The difference depends on 

 

 

However, as the magnetic flux is distorted and weakened by the load current a further change 
occurs to the voltage characteristic curve. The voltage drop resulting from the armature reaction 
approximately follows the load current more or less according to a quadratic function and, therefore, 
results in a slightly curved speed voltage curve when under load. Suitable design measures, 
however, make it is possible to keep the field distortion caused by the armature reaction extremely 
low. The max. permissible load current is provided for the respective machine type; however, the 
linearity errors listed in the selection tables refer to the current resulting from termination with the 
optimum load resistance. (F

rel

 = 0.2‰, at max. permissible current 5‰.)
