Abstract
A coil of a stator winding of an electric machine is formed of a number of windings, which are wound together with a number of layers of a mica tape, on which a number of layers of a cover tape are in turn wound. The coil is a three-dimensional form-wound coil. The mica tape has a bending stiffness of less than 50 N/m according to specification IEC 60371-2:2004 and a static friction coefficient between the top side and the bottom side thereof of less than 0.7 according to specification ISO 8295:1995.
