In a direct-drive high-power A / C-axis bi-rotary milling head, torque is transferred by two parallel connected rotary direct drive motors in C-axis, therefore, the length of C axis is inevitable large, moreover, the transmission components of it are bearing high torque. The torsion deformation of C axis must compute accurately during the design process. The torsion deformation of the transmission components of C parts when C-axis is rotating is analyzed by finite element method, the racial deformation and the torsion deformation of the case when C-axis is locking are analyzed either, this computing can provide support for the design and improvement of this type of milling head.

Abstract. In this paper, a new type of maglev wind generator is proposed. The working principle, structure characteristics and the finite element analysis of the new maglev wind turbine are introduced. The generator consists of a 2 degrees of freedom (DOF) maglev generator and a 3 DOF hybrid magnetic bearing. An eight poles active magnetic bearing with external rotor is added into traditional direct-drive permanent magnet wind generator. The rotor ring is hollowed, which can leads to the self-decoupling for magnetic fields between power generation system and suspension system. Compared with the conventional maglev wind generator, the proposed generator not only shows the same advantages of traditional maglev wind turbines, but also improves the axial length utilization and decrease the cost of motor control.
