Electromagnetic Hysteresis Based Dynamics Model of an Electromagnetically Controlled Torque Coupling [PDF]

Processes, 2019
This paper proposes a novel computationally efficient, easy-to-implement electromagnetic hysteresis based dynamics model of a kind of intelligent electromagnetic torque controlled coupling (EMTC), which, with drag torque under consideration, first models the electromagnetic hysteresis existing in the primary clutch with the classical Preisach model ...

Electromagnetic force and torque derived from a Lagrangian in conjunction with the Maxwell-Lorentz equations

, 2021
Electromagnetic force and torque are typically derived from a stress tensor in conjunction with Maxwell's equations of classical electrodynamics. In some instances, the Principle of Least Action (built around a Lagrangian) can be used to arrive at the ...
