摘要: An insulating tape having a mica layer, a reinforcing layer having a filler and a fiber reinforcing material laminated on the mica layer, and a cellulose derivative layer laminated on the reinforcing layer is provided. One or more hydroxyl groups in the glucose units of the cellulose derivative are substituted with a functional group such as —CH2CH2OH or —(CH2CH2O)pH (where p is any repeating number up to 50). The weight per unit area of the mica ranges from 100 g/m2 to 200 g/m2. The filler has a maximum particle size of 100 μm or smaller and a weight per unit area ranging from 10 g/m2 to 50 g/m2. The insulating tape is useful to form a stator coil insulating layer with high thermal conductivity, with no outflow of a filler to the exterior during production of the stator coil, and with enhanced bonding strength.

摘要: An insulating tape including: a mica layer containing mica; a reinforcing layer that is laminated onto the mica layer and contains a filler and a fibrous reinforcing material; and a flat sheet layer that is laminated onto the reinforcing layer and contains flat sheet-shaped inorganic particles having an aspect ratio of at least 30. In this insulating tape, the filler is supported in advance, and does not therefore flow out during manufacture of a stator coil, for example during hot-pressing. As a result, an insulating coating exhibiting high thermal conductivity can be formed.

摘要: The present invention provides a solvent-free varnish composition, including: a thermosetting resin (A) having two or more (meth)acryloyl groups in a molecule thereof; a thermosetting resin (B) having one or more epoxy groups in a molecule thereof; a monofunctional vinyl-based monomer having an ether bond or an ester bond; an organic peroxide having a 10-hour half-life temperature of 40° C. or more; and a curing catalyst for an epoxy resin, in which a mixed resin of the thermosetting resin (A) and the thermosetting resin (B) has an epoxy equivalent of from 500 to 5,000. The solvent-free varnish composition can be used as an insulating varnish that shows a small energy loss and requires a short curing time in its curing treatment step, and that provides a cured product that barely causes the precipitation of an oligomer or the like even when exposed to a refrigerant-based environment containing a refrigerant and a refrigerating machine oil under high temperature and high pressure.
