Load testing measurement of car alternator (generator) Supplying the electric power stably is one of the important issues in recent years as a lot of electrical equipments are used in the car. Then, the importance of the alternator has increased. The ability requested to the alternator is not only power generation. A highly effective and intelligent ability are required like a regenerative braking system to the aspect of energy saving technology. This example shows the velocity variations, which measured at two simultaneous channels as inside and outside of the clutch. And, because the difference of the velocity variation (WF: Wow and Flutter) in two places can be operated, a dynamic measurement is possible accurately in any rotation. MODEL-2021 uses the optical method for velocity measurement. This method is Non-contact measuring system therefore the measurement does not require the alignment of axes and coupling such as for a rotary encoder. The measurement result by using this system has no interference from colours and any other status on the surface of the object, and also this optical measuring method does not apply any pressure on rotations. This feature is available for detecting imperceptible value of velocity variation.
