Abstract
Power may be segmented either at the converter, using a multilevel inverter, either at the machine, by performing a polyphase winding. Moreover, increasing numbers of phases enables improved power quality and reducing torque ripples with the advantage of fault tolerance related to the loss of one or more phases. This class of system offers a reduction of design time, costs and the optimization of the volume of embedded systems. The objective of this work is to order, model and characterize the behavior of a training system multimachines composed of two five phase synchronous permanent magnet motors connected in series using two static converters.
Highlights
Thanks to the advances in technology and the means of calculating the powerful, it is possible to consider the variable speed applications in an efficient manner where the association of electrical machines and of static converters are more and more applications in embedded systems, where the gain in space and weight requires a very particular attention
An example of the systems of drives, which combine the advantages offered by the use of multiphase machines, of the electronic power and the means of calculation, is the SMM which allows you to order in a way completely decoupled several electrical machines whose windings are connected in series
We focus in particular on the modeling and the independent control of the two five phase synchronous permanent magnet motors connected in series
Summary
Thanks to the advances in technology and the means of calculating the powerful, it is possible to consider the variable speed applications in an efficient manner where the association of electrical machines and of static converters are more and more applications in embedded systems (ships, submarines, vehicles, aircraft...etc.), where the gain in space and weight requires a very particular attention. The traction systems electric railway are complex, they have electrical couplings, magnetic and mechanical solid. These couplings impose a number of constraints that complicate the modeling and analysis of these systems. Several configurations are developed and analyzed in order to guarantee the stability of operation when a mechanical disturbance or electric appears. In this approach, we focus in particular on the modeling and the independent control of the two five phase synchronous permanent magnet motors connected in series
