Permanent magnet planar micro-generators
Sensors and Actuators A: Physical, 2006Abstract Different types of axial-flux permanent magnet electromagnetic μ-generators have been developed in LEG in collaboration with Laboratoire d’Electronique de Technologie de l’Information (LETI), CEA Grenoble. A O8 mm planar generator consists of a permanent magnet disc rotor cut out of bulk SmCo5 or NdFeB, and a silicon stator with ...

Short-Circuit Analysis of Permanent-Magnet Generators
IEEE Transactions on Industry Applications, 2009Permanent-magnet generators (PMGs) have rapidly become important in renewable energy systems, portable and standby generating systems, and in many new applications in industrial, utility, aerospace, and automotive sectors. While there has been some discussion of “fault tolerance” and fault testing of an 8-MW machine has recently been reported [1 ...

Study on permanent magnet thickness of high-speed permanent magnet generator
Electrical Engineering, 2019The permanent magnet thickness (PMT) is an important parameter in the design of the permanent magnet machine, and it directly affects the air-gap magnetic field and performance of generator. In this paper, a 117-kW, 60,000-rpm, high-speed permanent magnet generator (HSPMG) is taken as an example, and a two-dimensional finite element model (FEM) is ...

Compact Permanent-Magnet Generator for Hybrid Vehicle Applications
IEEE Transactions on Industry Applications, 2004In hybrid electric vehicle (HEV) drive-trains an electrical generator is coupled onto the shaft of an internal-combustion engine (ICE) in order to process either the entire or a given fraction of the traction power required by the vehicle wheels.

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 ...

Axial Flux Permanent Magnet Controlled Generator
2018 IEEE 3rd International Conference on Intelligent Energy and Power Systems (IEPS), 2018This paper deals with axial flux permanent magnet generator with extended functionality which allows to control magnetic flux to change output voltage and stabilize external characteristics of generator. A mathematical model of electrical machine in the coordinate system (d-q) was obtained to simulate transients and external characteristics in Matlab ...

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.
