Abstract
In this paper, linear time--periodic system dynamics in
rotor vibration of electrical machines is examined. We
consider a two-pole cage induction machine equipped with
a built--in force actuator for active generation of
lateral force on the rotor.
The main contribution of the work is to identify and
model the sources of time-periodic system dynamics
in the coupled electromechanical actuator-rotor system.
Especially, the effect of higher spatial harmonics of the
magnetic field on the generated force is considered. In
this work, a linear time--periodic model for the
actuator-rotor system is derived. The parameters of the
analytical model are estimated by using time-stepping
finite-element analysis of the machine.
