Winding core type non-saturated reactor with air gap

摘要

The present invention provides a non-saturation reactor instead of downsizing is achieved is high performance low inductance values ​​of high and manufacturing cost in the gap with core type non-saturation reactor using the EI type punching electromagnetic steel sheet up to this. This is used wound iron core structure where the magnetic resistance is lowered after it is mounted wound around the wound frame after it is cured and dried by an insulating varnish on the winding core by a thin blade disc-shaped grinding wheel in A high permeability to the core portion void was to resolve the gap with core type non-saturable reactor that can be applicable to inductance change is less miniaturization of the new tool means for cutting developed manufacturing challenge the. .BACKGROUND 2
