Abstract:

In this paper, the thermal behavior of a 12kW, 12000rpm, wet-type Permanent Magnet Brushless DC motor (BLDC) with skydrol oil inside designed for electro-hydraulic actuation system (EHA) was analyzed. A 3-D computational fluid dynamics (CFD) model has been built. The influence of skydrol hydraulic oil in thermal behavior at both low-speed and high-speed conditions was discussed. The results confirm that the skydrol oil passing through the motor has different impact on the thermal performance in different conditions.
