Monitoring of power factor for induction machines using estimation techniques [PDF]

, 2015
Power factor is a significant element in power systems which is defined as the angle difference between voltages and currents that produces power fluctuation between sources and loads.

Influence of pole-pair combinations on the characteristics of the brushless doubly fed induction generator [PDF]

, 2020
The brushless doubly fed induction generator (BDFIG) is an alternative to the doubly fed induction generator (DFIG), widely used in wind turbines which avoids the need for brush gear and slip rings.

Transient System Model for the Analysis of Structural Dynamic Interactions of Electric Drivetrains

Energies, 2021
In electric drivetrains, the traction machines are often coupled to a gear transmission. For the noise and vibration analysis of such systems, linearised system models in the frequency domain are commonly used.

Energy-efficient motors [PDF]

, 2008
The use of a copper-squirrel cage in induction motors has been analyzed testing a prototype rated 1.1 kW and comparing the performances with a twin machine with an aluminum cage. The comparison has been made using torque, efficiency, starting torque, and
