Title:
STATOR FOR DYNAMO-ELECTRIC MACHINE, ROTOR FOR DYNAMO-ELECTRIC MACHINE AND DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2014212671
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To ensure the grounding of a core more than conventional, by suppressing occurrence of wear even when a stator is subjected to vibration over a long term.SOLUTION: In a stator for dynamo-electric machine having a stator core 41, a winding wound around the stator core 41, and a spindle 70A (fixed member) for fixing the stator core 41, one or more slit 711 is provided in the spindle 70A (shaft), and a protrusion 413 on a surface where the stator core 41 faces the spindle 70A is constituted to be hooked to the slit 711. With such a constitution, wear between the stator core 41 and the spindle 70A can be suppressed even when the stator is subjected to vibration over a long term. When the spindle 70A is conductive, it can be made to conduct the stator core 41, and thereby potential variation of the whole stator for dynamo-electric machine due to aging can be suppressed. Consequently, low noise performance can be guaranteed over a long period.
