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.

Optimum Magnetic Circuit Configurations for Permanent Magnet Aerospace Generators
IEEE Transactions on Aerospace and Electronic Systems, 1985In the design of high-speed low-power electrical generators for unmanned aircraft and spacecraft, maximization of specific output (power/weight) is of prime importance. Several magnetic circuit configurations (radial-field, axial-field, flux-squeezing, homopolar) have been proposed, and in this paper the relative merits of these configurations are ...

Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation
IEEE Transactions on Magnetics, 2011This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without neglecting their remanent field.
