Abstract

A motor core has multiple silicon steel sheets and multiple layers of electrically insulating colloid. Each one of the multiple layers of electrically insulating colloid is disposed between adjacent two of the silicon steel sheets. This reduces the chance of forming eddy currents, reducing the eddy current loss of the motor core during operation.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A motor core comprising:
 multiple silicon steel sheets; and   multiple layers of electrically insulating colloid each disposed between adjacent two of the silicon steel sheets.   
     
     
         2 . The motor core as claimed in  claim 1 , wherein each layer of the electrically insulating colloid is annularly arranged at spaced intervals on upper and lower faces of corresponding two of the silicon steel sheets, so that a gap is formed between the corresponding two of the silicon steel sheets.
