A binding cord for a motor (i) reduces damage to a motor component that is bound with the binding cord, (ii) has high fastening properties when the binding cord is tied, (iii) does not loosen after the binding cord is tied, (iv) prevents fluff from falling off, and (v) is suitable for both mechanical binding and manual binding. A binding cord for a motor of the present invention includes a multifilament yarn made of synthetic fibers. The multifilament yarn is a bulked yarn that has a loop and a slack in the direction of the yarn axis. The multifilament yarn is preferably a non-torque type and processed by a fluid jet. The degree of bulkiness of the multifilament yarn is preferably 1.5 ml/g or more.

Binding cord for motor

The protective sleeve for a motor component of the present invention is obtained by braiding multifilament yarns made of synthetic fibers into a cylindrical braided cord of at least 24 strands. The multifilament yarns have a single-yarn fineness of at least 15 dtex but less than 30 dtex and the yarn total fineness of a single braid unit of the braided cord is in the range of 800 to 1500 dtex. This protective sleeve has good covering properties and few voids. Therefore, a protective sleeve for a motor component is provided that has high partial discharge characteristics (electrical insulation performance) and good electrical insulation properties even when a step of washing away the raw yarn oil solution applied to the filaments was omitted.
