Abstract

PURPOSE: To circumferentially uniformalize the bending rigidity of a rotor without reducing the space factor of a magnetic pole section by applying an axial groove in the magnetic pole section of the rotor core and laminating and inserting a number of thin steel plates into it through a plate type matter with small wear coefficient.
CONSTITUTION: The groove 2a which is same as or similar to the slot 1 of the coil slot section 1a is axially arranged in the magnetic pole section 2 of the rotary core in such rotary core machines as two-pole machines. The laminated thin steel sheet 9 is inserted into the groove 2a through a plate type member 11 with small wear coefficient and pressed by the wedge 10. This permits the space factor of the magnetic pole section 2 not to decrease. Since the rigidity of the thin steel sheet 9 is small, the effect of the existence of the groove 2a cannot be dicreased and bending rigidity can be uniformalized.
