Ciencia, Docencia y Tecnología is a refereed, multidisciplinary open access scientific journal that aims to contribute to the development of scientific knowledge in Argentina and Latin America. Since 1990 it has been edited and funded by the National University of Entre Ríos and publishes original research articles in Spanish and Portuguese by national and international researchers. Until 2020, CDyT was published in May and November. As of Num. 62 may-ago (2021), it adopts the continuous publication mode, publishing three issues in April, August and December.
About the JournalAbstract
This work deals with different aspects regarding the construction and commissioning of the prototype for an eddy-current dynamometer designed to test electric motors.
In the introduction, the background and previous experiences with similar machinery are described. Afterwards, specific constructive details are given on the dynamometer and its power supply.
In the section on testing, the temperatures of both coils and discs are given, and tests at different loads are described.
Operating parameters such as magnetomotive forces, currents in the discs, torques and losses are calculated in the section on operating values.
Finally, in the conclusions, the advantages and disadvantages of this design are discussed, as well as the upgrades to be carried out for the equipment performance to improve.
