Impulsive Control of the Rotor-Stator Rub Based on Phase Characteristic
Abstract and Applied Analysis, 2014 An impulsive control method is proposed to eliminate the rotor-stator rubbing based on the phase characteristic. The relation between the vibration energy and the phase difference suggests the starting point for controlling the rotor-stator rubbing by ...

Bispectrum of stator phase current for fault detection of induction motor
, 2009 A number of research studies has shown that faults in a stator or rotor generally show sideband frequencies around the mains frequency (50 Hz) and at higher harmonics in the spectrum of the Motor Current Signature Analysis (MCSA).

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Fluid mixing in rotor/stator mixers [PDF]
, 1996 An industrial rotor-stator mixer was fitted into a flow loop to carry out overall power balance, flow visualisation and residence time distribution experiments. These were performed on various rotor-stator geometries and a half-scale unit. The overall

Design Theory of Stator and Rotor of PDM Based on Rack Gearing Principle
Shiyou jixie, 2020 The stator and rotor contour designed by the traditional line pattern design method is not smooth at the joint of the cycloidal arc and the arc, where the stator rubber is continuously worn during operation, which will accelerate the damage of the rubber
