Abstract
The speed of rotation can be advantageously measured using the laser D oppler principle. In the present paper, laser Doppler velocimetry (LDV ) is applied to measure the fluctuations in rotational speed of differ ent types of electric motors. Within an experimental study, it could b e shown that a measurement accuracy of the rotational speed of 0.015 % can be obtained with LDV-technique. Thus, high precise analyses of th e stability of rotational speed of technical drives can be performed. Compared to existing measuring methods, the accuracy of the LDV-method is superior.
