FERRITE CORES DEFLECTION YOKE
growing demand greater image clarity definition television images made necessary improvement ferrite cores deflection yoke. With advances ferrite technology, developed H44V ferrite materials with lower core loss than H44F. H44V material supplements existing H44F widely used many types televisions. also introduced ferrite materials suitable high quality picture displays with high horizontal scanning frequency. Although this catalog presents standard ferrites ferrite products, only design produce type customized core made-to-order basis, welcomes inquiries custom-design cores.

Working mechanism rotary transformers
Rotary transformers designed transmit electric signals from rotating body fixed body, from fixed body rotating body. this regards, possible lead wires transmit electric signals between rotating fixed body; although theoretically possible, spring brush used motors applied this task, noise problems will arise very weak signals very high MHz-level frequency involved. Consequently, rotary transformer created, which could transmit magnetic fields generated between rotor stator, through ferrite material (see righthand diagram). this diagram, performance magnetic circuit depends almost totally precision gap. conventional VCRs, between 30µm 50µm.
