PRODUCTION CAPABILITY CORE
The core is critical to determining such important factors as iron losses, vibration, sound levels and thermal stability, from a mechanical point of view it is important to design the core taking into consideration heavy lifts in the workshop, clamping impacts during transport and stresses due to disturbances in the network resulting in short circuit current.
All cores are manufactured from cold-rolled grain-oriented electrical sheet steel coated with oil resistant inorganic material. Normal-oriented or laser treated super-oriented electrical steel may be selected depending on sound level requirement and evaluation of losses.
The lamination of large cores is held together by means of fiberglass type which has been wound on under tension and cured to form a homogeneous cylinder.
