Eccentricity Fault Diagnosis Studying for a Round Rotor Synchronous Machine

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...

A New Method for Computation of Axial Flux Permanent Magnet Synchronous Machine Inductances under Saturated Condition

Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...

Characteristics of ventilation circuits applied to cylindrical rotor synchronous machines

The use of cylindrical rotor in synchronous machines offers excellent conditions for the heat dissipation from the stator and rotor windings. This paper describes the main ventilation arrangements for this type of construction as well as specifies the main factors that determine the choice of the most appropriate ventilation method for each application.
