Mission and objectives

Establish statistical models of the characteristics
of magnetic laminations which will be made
available to designers of electrical machines.

From the magnetic, mechanical & chemical characteristics
of the batches of magnetic sheets received at Nidec
(over the last few years) : establish the statistical
distributions associated with each of the characteristics
according to the grades and the suppliers then update
the types identified in the Nidec specification.
Establish the most appropriate distribution laws for
the context
Establish the laws of polarization (field),
losses (polarization) and associated dispersions
from measurements taken, statistical data and
estimated values ​​of polarization at saturation
(depending on the chemical composition)

The objective is to be able to estimate the effect
of the dispersions of characteristics of the lamination
steel delivered, on the performance of the machines
