Influence of static and dynamic rotor/stator misalignments in axial flux magnetically geared machines

open access: yesThe Journal of Engineering, 2019
Here, static and dynamic (rotating) misalignments between the low-speed rotor (LSR) and the stator of axial flux magnetically geared machines are studied with the aid of 3-D finite element analysis (FEA).

Non-Uniform Clearance between Rotor Surfaces and Its Effect on Machine Performance in Twin-Screw Compressors

open access: yes, 2012
The performance of twin-screw compressors is primarily affected by the clearance between a pair of meshing rotors. This study proposes a method for calculating the normal clearance along the contact line between rotors using two normal rack curves, which
