the superexcitation and efficiency relation in a short-stroke pulsed electromagnetic motor of a seismic source
The article analyzes the influence exerted by the shape of excitation current pulse in a short-stroke pulsed electromagnetic motor of a seismic source on the mechanical energy, energy loss and efficiency of the electromagnet, with regard to a drop in magnetomotive force in magnetic circuit and effect of the current displacement in conductive tracks in the magnet winding.
