GALLO, Omar D; GONELLA, Rubén M. J; FERREYRA, Diego M  and  DIAZ, Alberto J. Freno de corrientes parásitas para ensayo de motores eléctricos. Cienc. docencia tecnol. [online]. 2017, n.54, pp.283-296. ISSN 1851-1716.

This work deals with different aspects regarding the construction and commissioning 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.

Keywords : Eddy currents; Dynamometer for electric motors; Motor testing.
