Computation of the voltage-driven flux-MMF diagram for saturated PM brushless motors [PDF]
, 2005 The flux-MMF diagram or "energy conversion loop" is a powerful tool for computing the average torque of saturated permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are violated, as they often are in modern ...

Analytical and numerical computation of air-gap magnetic fields in brushless motors with surface permanent magnets [PDF]
, 2000 This paper extends the theory of the air-gap magnetic field in permanent-magnet (PM) brushless motors. Scalar and vector potential solutions to the field equations are brought together to unify many of the important practical methods already in use.

Advanced Science, EarlyView.Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Advanced Science, EarlyView.The human brain's imagination, which enables autonomous driving hazard avoidance by completing missing visual information, relies on Gaussian‐stochastic neuron. We report the altermagnetic RuO2 spintronic neurons integrating field‐free switching and intrinsic Gaussian stochasticity, building an all‐spin ANN for high‐quality image repairing and high ...

The Torque Characteristic Analysis and Simulation on Electromagnetic Gears
Energy Procedia, 2012 AbstractThis paper analyzes the effect of air-gap changes, loading currents, claw-pole and angle between driving wheel and driven wheel on electro-magnetic gears torque. ANSYS simulation result shows: torque decreases geometrically with the increase of the working air gap thickness, with the internal gear air-gap decrease with circumferential air-gap ...
