Linear Reciprocating Generators with Permanent Magnets
Russian Electrical Engineering, 2019Designs of linear generators with permanent magnets for electric shock absorbers are considered. The inductor or armature is moved by generators with a fixed armature and the generators with a fixed inductor. Generator armature windings are used to stack windings in slots and slotless windings.

Ultraminiaturized Milliwatt-Scale Permanent Magnet Generators
TRANSDUCERS 2007 - 2007 International Solid-State Sensors, Actuators and Microsystems Conference, 2007This paper reports the design, fabrication and experimental characterization of ultraminiaturized, axial-flux, permanent-magnet (PM) generators intended for milliwatt range systems. The miniaturization of PM machines is attractive because scaling laws are favorable, but integration of ultra-small permanent magnets is challenging.

Permanent magnets for self-regulating generators
Journal of Materials Engineering, 1991Self-regulating permanent magnet generators (PMGs) apply rare earth magnets for providing excitation during their operation. This paper explains the operating principle of the self-regulating PMG and correlates the performance requirements with the characteristics of rare earth permanent magnets.

A Permanent Magnetic Brushless Generator with Magnetic Circuit Control
2020 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2020at present, the permanent magnet alternator on the market switches the working state according to the charging and discharging conditions of the battery. It uses the electronic switch to cut off the load of the generator to stop charging the battery. This method makes the generator in no-load state, which will not only reduce the fuel efficiency of the

Pole magnets segmentation effect on permanent magnet synchronous generators
2017 International Conference on Electromechanical and Power Systems (SIELMEN), 2017This paper presents the analysis of using segmented permanent magnet instead of single pole units on a synchronous generator. The main reason of using such solutions is the fact that smaller, simple shapes permanent magnets with standardized dimensions can easily be found on the market at low costs.
