“…This means that no brushes or slip rings are required. This motor has been widely considered in the literature as an inner-rotor motor for use in superconducting and high-speed applications due to its current-based excitation and robust rotor structure, and as a high frequency generator due to its parallel arrangement of poles requiring no additional ampere-turns of field winding for an increased number of poles [12][13][14][15][16][17].…”

“…The magnetizing flux passing through the stator shaft, airgap, and rotor sleeve must be equivalent, which can be used to express the following dimensions as a function of the airgap radius r g : the axial length of each stator/rotor section (14), the inner radius of the rotor sleeve (15), and the outer radius of the rotor sleeve (16).…”

Flywheel energy storage technology has been successfully commercialized for applications requiring high power, high cycle-life, and short storage intervals. High idling losses have prevented the use of flywheel technology in applications that require longer storage intervals, such as grid-based, load-following energy storage. This paper proposes the use of an outer-rotor ac homopolar motor to significantly decrease idling losses, increase energy density, and decrease cost. Motor sizing equations, a comparison to the typically-used permanent magnet motor, and 3D finite element analysis of an example design are presented. It is shown that for high-performance flywheel designs, the ac homopolar motor can have a torque density comparable to that of a permanent magnet motor.

The research is devoted to the investigation of NdFeB permanent magnet (PM) based synchronous generators with non-overlapping concentrated windings. The rotor of such a generator has 10 pole pairs (PMs), which is dictated by the nominal voltage frequency (f=50 Hz) and the rotational speed (n=300 RPM). Comparison is made for four generators with three-phase winding coils and stator tooth numbers 18, 21, 24 and 27.
