This paper presents a simulation technique of the coupling system with electromagnetic system, hydraulic system and rigid body system for dynamic simulation of rigid body system driven by the electric motor. From the fuel consumption improvement point of view, the electric drive system is applied to the construction machinery using the electric motor which can regenerate the slowdown energy effectively. Permanent magnet synchronous motors (PMSM) that have the features of small size and high efficiency characteristics are put into general use to the electric drive system. Therefore, it is important to consider the magnetic characteristics of the PMSM for the evaluation of the electric drive system. This simulation technique has an outstanding feature for numerical stability by considering strong-coupling analysis with electromagnetic system, hydraulic system and rigid body system by formulating the PMSM characteristics using mathematical models considered magnetic saturation and cross-coupling effects. It is verified that the simulation technique is valid for the actual system by comparing the test results using the HILS system for the electric motor with the dynamic simulation ones.
