TLDR
In this article, the concepts of natural frequency, critical speed, excitation, mechanical resonance, damping, torsional excitation and critical speeds are defined and placed in context.Abstract:
The concepts of natural frequency, critical speed, excitation, mechanical resonance, damping, torsional excitation, torsional critical speeds, unbalanced magnetic pull, and magnetic instability are defined and placed in context. The author seeks to encourage the use of technically justified words and phrases in the technical literature. The article is presented in a context of a technical survey and a tutorial. >read more

Dynamics of rotating machines
TL;DR: In this article, the reader can understand the dynamics of rotating machines by using extremely simple models for each phenomenon, in which (at most) four equations capture the behavior of rotor vibration.

Electromechanical interaction in rotordynamics of cage induction motors
TL;DR: In this article, an electromechanical rotor model is derived on the basis of the Jeffcott rotor with two additional variables for the harmonic currents of the rotor cage, and the rotordynamic effects of this model are studied.

Rotordynamic analysis of different rotor structures for high-speed permanent-magnet electrical machines
TL;DR: A rotordynamic analysis of two different high-speed permanent-magnet electrical machines has been performed as mentioned in this paper, where rotors are analysed separately and for each of them the analysis is performed for three different types of constructions depending on the type of retaining sleeve.

Oscillatory Torques During Synchronous Motor Starting
TL;DR: In this article, the effects of twice-slip frequency torques on mechanical system considerations such as critical speeds and stress buildup in shafts are discussed, and specific areas of design coordination between designers of electrical power systems, synchronous motors, and the mechanical components of the system are suggested.
