Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]

open access: yes, 2003
A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and

Brainless Walking: Animal Gaits Emerge From an Actuator Characteristic

open access: yesFrontiers in Robotics and AI, 2021
In this study, we discovered a phenomenon in which a quadruped robot without any sensors or microprocessor can autonomously generate the various gait patterns of animals using actuator characteristics and select the gaits according to the speed.

Research on the Accumulative Damage of Flywheels Due to In-Space Charging Effects

open access: yesAerospace
High-speed rotating flywheel bearings, designed for space applications, generate a high-resistance hydrodynamic lubrication film, which isolates the rotor, transforming it into a conductor. This phenomenon introduces a novel failure mode—flywheel bearing
