Title:
FITTING TOOL DOUBLING AS MAGNET IC POLE OF "LEFT-HANDED-THREAD WINDING/GAP/RIGHT-HANDED-THREAD WINDING" TOROIDAL CORE, AND COOLING PIPE
Document Type and Number:
WIPO Patent Application WO/2014/087890
Kind Code:
A1
Abstract:
In configuring a toroidal core used for a rotary electric machine, a wound iron core is easier to manufacture and less expensive than a laminated iron core made by pasting cut-out members together. However, use of the wound iron core in a toroidal core has a drawback in that the configuration of the sharp angles and shaft-mounting locations for attachment is more difficult than with a laminate d iron core, making it difficult to attach the wound iron core to a shroud or a rotary duct. Among toroidal cores composed of the wound iron core, a "left-handed-thread winding/gap/right-handed-thread winding" toroidal core has a gap portion and the refore permits an aggregate of electromagnetic steel sheets or a fitting tool configured from at least one of a soft magnetic ceramic, a soft magnetic sintered metal, and a soft pressed powder magnetic materi al to be put into this gap portion, whereby the toroidal core can be easily attached to a shroud or a rotary duct structure, an excellent magnetic circuit can be formed, and an opening for a cooling pipe to pass through can be created in the gate section of the fitting tool.
