Title:
LAMINATED CORE AND MOTOR USING THE SAME CORE
Document Type and Number:
Japanese Patent JPH07111745
Kind Code:
A
Abstract:

PURPOSE: To form a laminated plate of high silicon steel plates and to fix the plates to each other by welding in a laminated core formed by laminating the plates.

CONSTITUTION: High silicon laminating plates 2 punched from silicon steel plates each containing 6.5% of silicon content and low silicon laminating plates 3 punched from silicon steel plates each containing 1.5-3% of silicon content are alternately laminated, the laminated plates 2, 3 are fixed to each other by bead welding 5 to form a laminated core 1. Since the plates 2 containing 6.5% of silicon content has extremely low core loss, a core loss as the whole core 1 can be reduced. Even if weldability of the plate 2 is wrong, the plate 3 has excellent weldability, and hence the plates 2, 3 can be integrated with each other by welding.
