Abstract :
The present paper investigates the effects of rotation on flow resistance of the flow passing through the rotor-stator gap of radial flux electrical machine. Rotational pressure loss was measured and compared with the results predicted using computational fluid dynamic (CFD) methods. By using dimensional analysis, correlation for the shock loss coefficient is proposed. It provides a significant contribution to the field of thermal modelling of electrical machines, such as thermofluid modelling using Motor-CAD.
