The principle of operation of a tachogenerator, being the dual of an electric motor, is also based on Faraday’s law of electromagnetic induction which states, as shown by eqn (2), that: the magnitude of a voltage induced in a single loop conductor is proportional to the rate of change of lines of forces passing through (or linked with) that loop. WEG Standard Product Catalog (Motors, Enclosed Motor Controls, Gears, and Alternators) WEG Automation Catalog: LV Variable Frequency Drives and Soft Starters (Full Catalog) / Power and Controls Products Catalog. Although a voltage divider could theoretically be used with a tachogenerator to extend the measurable speed range in the volt scale, it is not advisable to significantly overspeed a precision instrument like this, or its life will be shortened. Tachogenerators can also indicate the direction of rotation by the polarity of the output voltage. The basic constructions of DC tachogenerator are shown in fig. The dc tachogenerator is a small dc generator. The armature is driven by motor shaft whose speed is feedback. The rotor iron cored and field is a permanent magnet. The armature of a dc tachogenerator is Author: Author: Technical Editor.APPLICATIONS. The WEG tachogenerators have been designed for applica- tions on servocontrol operating machines, driving of textile machines, accelerators. Tachogenerators. 1.
