Abstract
This paper describes design changes on rotor ventilation system of the air-cooled synchronous machine. There are several variants for the analysis. This research is performed to find possible ways for increase of the power output of the machine. The rotor cooling system uses an under winding cooling channel to distribute the cooling air in the axial direction into the rotor and then through the radial rotor channels into the air gap. The presented optimization of the rotor cooling system is in the angle pitch of the radial channels. These changes had to be verified, before it could be implemented to the actual machine. Computational Fluid Dynamics tool Ansys Fluent is used for the simulations. The changes have positive effect on pressure drop, airflow and air temperature.
