Title:
STATOR OF ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS6035932
Kind Code:
A
Abstract:
PURPOSE:To enable to double the insulating lifetime by switching to shortcircuit neutral leads to supply power voltage to the primary leads and to shortcircuit the primary leads to supply the power voltage to the neutral leads. CONSTITUTION:The primary leads 4-6 are provided at the starting ends 1a-3a of 3-phase stator windings 1-3 having starting ends 1a-3a and finishing ends 1b-3b of the phases, and the finishing ends 1b-3b are provided at neutral leads 7-9. It is switched to shortcircuit the neutral leads 7-9 by a shortcircuiting bar 10 to supply a power voltage to the leads 4-6 and to shortcircuit the primary leads 4-6 by the shortcircuiting bar 10 to supply the power voltage to the neutral leads 7-9.
