Rezumat
Frana electromagnetica cu pulbere (FEP) este un dispozitiv antidemaraj de transmisie a puterii, de design
simplu, greutate redusa si dimensiuni mici, bine adaptata la cerintele din industria grea. Lucrarea prezinta o FEP,
alternativa cu rotor de gabarit, de 200 Nm, viteza de 1000 / min, reprezentat simplificat in figura 1. Luand in considerare avantajele de utilizare a acestor dispozitive, s-a stabilit experimental ca valoarea optima a intrefierului de lucru este de 1,6
mm. Teoria FEP si alte rezultate cu privire la proiectarea si experimentarea lor sunt prezentate in [1,2 ... 5]

Abstract
The electromagnetic powder brake is a disengage power transmission contra device, of simple design, low
weight and small size, well adapted to the requirement of the heavyindustry. This study presents an electromagnetic
powder brake, the alternative with rotor of mail weigh, 200 N.m, 1000 speed/min.. Taking into account the advantages of
using thesedevices we found experimentally that the best field coil is the one of 1,6 mm.
