Jm. Biedinger et Jp. Vilain, DESIGN OF LOW-VOLTAGE VARIABLE-FREQUENCY ELECTRICAL MOTORS - I - ANALYSIS OF THE MAGNETIC-THERMAL-ELECTRIC COUPLED PROBLEM, EUROPEAN PHYSICAL JOURNAL-APPLIED PHYSICS, 3(1), 1998, pp. 101-118
In this paper, the authors present a model for the multidisciplinary o
peration analysis of a variable frequency electrical drive, in the cas
e of low voltage supply. This model takes into account the coupling be
tween the electromagnetic; thermal and electrical phenomena. It allows
to evaluate the performances under permanent or transient thermal con
ditions, as we can find in the working cycles of electrical vehicles w
ith on board energy supply. This model is a part of an optimal design
procedure, which will be described in an other article. For this reaso
n, this paper is devoted to explain the dependences between the design
variables and the performances. The proposed model is applied to a pe
rmanent magnet brushless DC motor. The performances are evaluated for
the S1 and S2 duty-cycling operations. The influence of the driving pa
rameters of the converter is also examined.
