<p>In accordance with the method of obtaining effective energy from the ferromagnetic material which is the core of electromagnet, its winding is supplied with electric current with such intensity that it causes magnetic saturation of the core, and after the work of attracting the armature is done, the supply is disconnected without loss of passive energy accumulated in the electromagnet inductance. A resonant impulse power supply is used to supply the electromagnet.</p> |
