WebApr 1, 2024 · CFM56 is one of most widely used dual-rotor aero-engines [27].Based on the basic structure of CFM56, a two-disk dual-rotor system supported by four points is obtained by using the simplified method of dynamic model [28].The schematic diagram of the dual-rotor system with inter-shaft bearing is shown in Fig. 1.The HP rotor and the … A dual-rotor permanent magnet induction motor (DRPMIM) is a motor having two rotors within the same motor housing. This rotor arrangement can increase power volume density, efficiency, and reduce cogging torque. Some dual-rotor permanent magnet induction motors are a type of induction motors, while others are not actually induction motors.

WebJul 25, 2024 · The 3D model of the dual-rotor system is built by Inventor and saved in “x_t” format, which is then imported into ADAMS software, as shown in Fig. 2. The material used in ADAMS is structural steel (E = 2.07 × 10 11 N/m … WebFor special rotor systems, different kinds of methods should be applied. For example, when balancing the dual-rotor system of an aeroengine, if balancing the inner and outer rotors separately, the system unbalance would occur even if a single rotor has been balanced. Therefore, a specific balancing method should be developed for dual-rotor systems. WebSep 18, 2024 · 2.2 Finite Element Model of the Dual-Rotor System. The dynamic model of the dual rotor system was established by using finite element method. The shaft end is modeled by a beam, and the disk is regarded as a rigid body. The rotational inertia of the shaft end and the disk are considered in the model [11–13]. 2.2.1 Rigid Disk Model help with pg\\u0026e bill fresno ca
