Optimum Magnetic Circuit Configurations for Permanent Magnet Aerospace Generators

IEEE Transactions on Aerospace and Electronic Systems, 1985
In 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, 2011
This 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.

Permanent Magnet Generator Rotor Containment Study

1983
Abstract : The design, development and testing of an advanced containment structure for high speed permanent magnet machines is presented. The primary intent of the program was to achieve a reduction in system weight, volume and cost through the use of an improved containment design.

ADVANTAGES OF PERMANENT MAGNET SYNCHRONOUS GENERATORS

Today, no one will be surprised by the fact that many relays and sensors, rotors of motors and generators, even in such grandiose structures as industrial hydroelectric power plants and wind turbines, use neodymium magnets in their units instead of the excitation windings that are becoming a thing of the past.
