Mechanical Models of Friction That Exhibit Hysteresis, Stick-Slip, and the Stribeck Effect.
Bojana Drincic
- 01 Jan 2012
TL;DR: In this paper, the Stribeck effect and butterfly hysteresis were investigated using a combination of masses, springs, and dashpots and the frictional phenomena emerged as the result of their interaction.

The Effect of the Electrical Steel Properties on the Temperature Distribution in Direct-Drive PM Synchronous Generators for 5 MW Wind Turbines
TL;DR: In this article, the effect of the magnetic and thermal properties of four electrical steel grades were compared for a permanent magnet synchronous generator (PMSG), and the influence of the steel grade on the thermal distribution was compared for four geometries of PMSG with varying air gap diameter and pole-pair number.
