N2 - It's known that electro-hydrostatic actuators (EHA) are characterized by rapid and obvious temperature rise on account of high integration and poor conditions for heat dissipation. In view of this situation, thermal circuit network of motor in EHA differs because thermal resistances occupy temperature-varying properties. Hence, thermal slide rheostat has been introduced into network newly in this paper to modify models. As the research base, brushless direct current motor (BLDC) with its components is abstracted to cylinder considering time-varying properties due to temperature-varying laws of thermal conductivities of different materials. Aiming at the cylinder, firstly, distribution and variation rules of two-dimension unsteady thermal field of it are calculated and discussed, with which time-varying properties of arbitrary node temperature can be consequently acknowledged. Secondly, results above are applied to develop thermal slide rheostat model and two-dimension dynamic thermal circuit network of cylinder. At last, corresponding simulations, relevant conclusions and necessary discussions are available to explain the novel model.
