According to one embodiment, there is provided a rotating electrical machine coil with a conductor and an insulation layer that is provided around the conductor to cover the conductor, the rotating electrical machine coil including a linear part of the coil and a coil end that is separable from and electrically connectable to the linear part of the coil.

Rotating electrical machine coil

An erosion resistant material has a continuous portion and discontinuous portions. The continuous portion has a continuous structure. The discontinuous portions are arranged inside the continuous portion to have a discontinuous structure. The discontinuous portions are formed of particles having an average particle diameter of 1 &#x3bc;m or less. Further, the discontinuous portions are formed of a material having a surface hardness and a Young's modulus higher than those of the continuous portion.

Erosion resistant material and turbine blade

The present invention provides a solution to the above-described drawbacks, and more specifically, as the tape-like or sheet-like insulation member, the resin matrix in which the first particles having a heat conductivity of 1 W/mK or higher and 300 W/mK or lower, that are diffused in the resin matrix, and the second particles having a heat conductivity of 0.5 W/mK or higher and 300 W/mK or lower, are diffused, is employed.

Highly heat conductive insulating member, method of manufacturing the same and electromagnetic device

A mica tape comprising a mica foil, a glass cloth, and an inorganic filler arranged on the glass cloth, wherein the mica tape is wound a plurality of times about an outer circumferential surface of a conductor portion of an electrical rotating machine coil so as to form an insulating layer for the coil, and the inorganic filler has a Mohs hardness falling within a range of 1 to 7 and exhibits a heat conductivity superior to those of the mica foil and the glass cloth, whereby, the inorganic filler is excellent in the heat conductivity and has a Mohs hardness not lower than that of the glass cloth contained in the mica tape, when used together with the inorganic filler.

MICA tape, electrical rotating machine coil, and electrical rotating machine comprising the electrical rotating machine coil

The invention aims to provide a highly heat conductive tape member or sheet member and a method for easily producing a highly heat conductive tape member or sheet member. The mica tape member or mica sheet member of the invention includes a mica-containing layer and a lining material, and the mica-containing layer contains scaly particles, particles having a heat conductivity of 0.5 W/mK or higher and a size of 1 &#x3bc;m or smaller, and a binder.
