Title:
FASTENING DEVICE OF VERTICAL ROTARY ELECTRIC MACHINE STATOR
Document Type and Number:
Japanese Patent JPS59129549
Kind Code:
A
Abstract:
PURPOSE:To prevent the production of a magnetic noise by employing a stopper as a rotary detent, thereby fastening a stator without restricting the radial thermal expansion of the stator. CONSTITUTION:A gap of 1mm. is spaced at the side faces of the outer periphery farther from the center of the periphery of a bolt 7 in the circumferential direction, and a stopper 8 is fastened to a stator in parallel with the side face. When an armature core 2 and a stator 4 thermally expand, the stator 4 radially displaces. When the stator 4 radially displaces, the stopper 8 radially displaced together with the stator 4. Accordingly, the stopper 8 does not interfere with the bolt 7.
