A bearingless synchronous motor (BLSM) is a special type of electric machine that
integrates the functions of traditional synchronous motors and magnetic bearings. It not only …

This article presents a novel structure of a bearingless motor with integrated passive axial
electrodynamic suspension. The simple initial structure has been improved in three steps …

This chapter considers energy stored in the form of mechanical kinetic and potential energy.
This includes well-established pumped hydroelectric storage (pumped hydro) and flywheels …

Passively levitated thrust self-bearing machines with combined armature windings have
recently been introduced. These machines reach higher reliability and compactness while …

Self-bearing machines offer a highly integrated solution to achieve the rotor drive and
magnetic levitation within a single structure. Although the trend is toward a diminution in the …

This article investigates a bearingless motor with passive electrodynamic axial suspension.
The axial suspension force is generated by a specific coil configuration called a figure-eight …

Self-bearing machines offer a highly integrated solution to achieve the rotor drive and
magnetic levitation within a single structure. Although the trend is toward a diminution in the …

This paper proposes a new configuration of five-axis passively stabilized bearingless
motors. The proposed machine is passively levitated without active magnetic suspensions …

Self-bearing machines have gained increasing interest over the past twenty years by
bringing the benefits of magnetic suspension to high torque density systems. Among them …

Passive magnetic levitation offers advantages in terms of compactness, reliability and cost
thanks to the absence of position sensors, controllers and power electronics dedicated to the …
