Document Type and Number:
WIPO Patent Application WO/2017/115681
Kind Code:
A1
Abstract:
Provided is a structure of an electrical connection section where a terminal 53 of an electroconductive component 50 of a motor and a winding 30 are thermally bonded together. The terminal 53 has: a locked part 53a that is located on the base side thereof; and a fused part 53b that is located on the tip side. The winding 30 has: an entwined part 31 that is wound on the locked part 53a and is connected at one end 36 to a fused ball 55 formed on a fused part 53b; and a connection wire part 33 that is stretched from a main winding section 34 disposed in the motor in a wound state and is connected to the other end of the entwined part 31. In addition, the one end 36 of the entwined part 31 is in a state in which a tensile force pulling the connection wire part 33 toward the main winding section 34 does not act thereon.
