            Abstract : 
The paper describes a method of modeling heat flow in flooded rotor electrical machines for electro-hydrostatic actuators. In particular, a novel technique for lumped parameter representation of the transient thermal behavior of hydraulic fluid in the airgap is presented. The technique has been applied to a flooded rotor brushless permanent magnet motor for an aerospace application, and it is shown that there is good agreement between measurements and predictions.
