Abstract
PURPOSE: To form a highly accurate core with a high rigidity and having a damper effect by securely welding the teeth of rotor cores laminated in the lamination direction of the core while at an equi-space with respect to the outer surface thereof.
CONSTITUTION: A concave part is provided on each end of teeth of slots 7 cut on rotor cores 6 laminated in such a manner that they continues in the lamination direction of the rotor core 6 while at an equi-space with respect to the outer surface of the core. All rotor cores are fixed together by welding the concave parts. The rotor core assembly thus obtained is large in the rigidity having a damper effect. Therefore, a high speed operation is made possible while a stable operation can continue against any load and the pulsation of the drive torque.
