FIELD: high-frequency current engineering and associated devices; induction build-up of parts for all industries. SUBSTANCE: for concentrating current on working surface of inductor, its nonworking surfaces are ribbed by means of wire soldered onto them; parameters of ribbed surfaces satisfy condition a > 0, b > 0, c > 0, where a is rib height; b is rib width; c is rib-to-rib distance, remembering that 0 is assumed as working surface roughness. EFFECT: enlarged functional capabilities. 7 dwgr |
