<p>PURPOSE:To constitute a three-phase wound core with low noise without deteriorating magnetic characteristics. CONSTITUTION:The three-phase wound cores comprise two inner wound cores 13 and one outer wound core 16. Each core has combination wound cores of first windings 11, 14 formed of directional silicon steel plates disposed at an inner periphery and second windings 12, 15 formed of 6.5%-silicon steel plates disposed at an outer periphery. Each core 13 is formed of a wound core made of a directional silicon steel plate, or only the core 16 may be formed of combination wound cores of a first winding 14 made of a directional silicon steel plate disposed at an inner periphery and a second winding 15 made of a 6.5%- silicon steel plate disposed at an outer periphery.</p> |
