The Wound Rotor Synchronous Machines (WR-SM) is very well known in the salient pole configuration for applications as electrical generator operating at constant speed. In this paper, the use of a WR-SM as motor for the electric traction of heavy electric vehicles is investigated. The main features of the proposed drive system are the capability to generate high torque at very low speed without excessive overload of the stator windings and to operate theoretically at constant power until unlimited speed. Therefore, the proposed drive system is very well suited to satisfy the torque and speed demand of heavy electric vehicles such as buses, trucks, industrial lift trucks and Light Rail Transit (LRT). The analysis of the control strategy, performed using a space vector approach in the d-q plane, has been firstly developed by means of a linear model of the machine and then it has been extended to non linear operating conditions. The effectiveness of the proposed drive system has been verified by experimental tests. Then the prototype has been installed as traction system of an electric fork-lift truck.

Abstract
The Wound Rotor Synchronous Machines (WR-SM) is very well known in the salient pole configuration for applications as electrical generator operating at constant speed. In this paper, the use of a WR-SM as motor for the electric traction of heavy electric vehicles is investigated. The main features of the proposed drive system are the capability to generate high torque at very low speed without excessive overload of the stator windings and to operate theoretically at constant power until unlimited speed. Therefore, the proposed drive system is very well suited to satisfy the torque and speed demand of heavy electric vehicles such as buses, trucks, industrial lift trucks and Light Rail Transit (LRT). The analysis of the control strategy, performed using a space vector approach in the d-q plane, has been firstly developed by means of a linear model of the machine and then it has been extended to non linear operating conditions. The effectiveness of the proposed drive system has been verified by experimental tests. Then the prototype has been installed as traction system of an electric fork-lift truck.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
