Diagnostics of Electromagnetic Friction Brakes and Clutches

This paper proposes and theorizes upon a new method for diagnosing movable-armature electromagnetic mechanisms (EM), which is based on an additional high-frequency electric-field effect on the EM magnetic core; the field excites corresponding high-frequency electrodynamic processes that are not related to the EM operating parameters and do not affect them in any way. The EM winding is used as an electromagnetic control sensor, which registers the diagnostic parameters of high-frequency electrodynamic processes, whose value depends on the current status of the EM.
