Abstract

A coil has a winding that is coated with an epoxy resin in at least some areas, wherein a ratio of a compressive strength of the epoxy resin to the tensile strength thereof at room temperature ranges between 2 and 5, the modulus of elasticity at room temperature is at least 5000 MPa, and at a glass transition temperature of the epoxy resin, the modulus of elasticity and the tensile strength have values amounting to at least 30% of the values at room temperature.
