Contributions to Elimination of Excitation Field Harmonics in Turbogenerators
Advances in Electrical and Computer Engineering, 2022 Turbogenerators driven by high-speed turbines are frequently used in electrical power generation. Power quality of a synchronous generator is directly associated with its excitation field harmonics. Conventional method to eliminate the most prominent harmonics is to distribute the slots to 2/3 of the rotor perimeter with equal slot pitches and ...

Harmonic response of GMR sensor under sinusoidal excitation field
Journal of Physics: Conference Series, 2011 In this work, we report the readout technique of the GMR magnetometer by detecting the odd-harmonic response under an sinusoidal excitation field. The time domain output waveform of the sensor is measured, and an analytical model is used to simulate its behaviour.

Traction Synchronous Machine with Rotor Field Winding and Two-Phase Harmonic Field Exciter
World Electric Vehicle JournalMany modern electric drives for cars, trucks, ships, etc., use permanent magnet synchronous motors because of their compact size. At the same time, permanent magnets are expensive, and their uncontrolled flux is a problem when it is necessary to provide a wide constant power speed range in the field weakening region.
