In the latter domain, slotless stators are recognized as the most suitable, as they deliver higher power density and lower speed-dependent losses. Nevertheless, the larger airgaps proper to slotless topologies minder bearing load capacities.In this study, a slotless and slotted drive designed for the same rotor are experimentally characterized. They are compared head-to-head in terms of passive stiffnesses and torque and force generation. A bearing control effort factor is also defined.rotating electrical machinesmagnetic levitationhigh-speedtext::conference output::conference proceedings::conference paper
