Brushless dc generator without permanent magnet
SPEEDAM 2010, 2010This paper presents characteristic analysis of a without permanent magnet Brushless dc (WPMBLDC) generator. Proposed configuration is a 9/6 BLDC generator in which permanent magnet is replaced with assisted field coil in the rotor. Due to dc current in the assistant field winding, the magnetic field flows axially through the rotor shaft and closes ...

Induced pole permanent magnet synchronous generator
2017 International Symposium on Electrical Machines (SME), 2017The design of an induced pole permanent magnet generator by retrofitting an induction motor is shown. The geometry was parameterized in order to explore the complete design panorama with the finite element method. The highest back EMF case was chosen and manufactured. The experimental results are analyzed and compared with the simulations.

Modular, permanent-magnet wind-turbine generators
IAS '96. Conference Record of the 1996 IEEE Industry Applications Conference Thirty-First IAS Annual Meeting, 2002Multipole, permanent-magnet, synchronous machines have been proposed as direct-coupled generators for large grid-connected wind turbines. A manufacturer would need to prepare a wide range of detailed designs and stock a large quantity of parts and materials to cover the range of likely sizes and ratings needed. Modular construction greatly reduces this

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.
