An electric machine may include a plurality of stator sections each formed from one or more stator laminations stacked to form a stator. The stator may have windings arranged therein to form magnetic poles. The stator may surround a rotor. A diamagnetic or paramagnetic stator layer may be interposed between at least one adjacent pair of the stator sections.

To provide a method by means of which stacks of metal sheets can be produced in an easy and efficient way, it is proposed that the method comprises the following: coating one or more metal sheets with a bonding substance; bonding multiple metal sheets to form a sheet-metal laminate by a first activation of the bonding substance; cutting up the sheet-metal laminate to produce multiple sheet-metal laminate units and/or cutting out multiple sheet-metal laminate units from the sheet-metal laminate; and bonding the multiple sheet-metal laminate units to form a stack of metal sheets by a second activation of the bonding substance, wherein the bonding substance comprises a resin material and an elastomer material.

A method for securing metallic first and second parts together includes positioning filler metal along an interface between the first and second parts. The first and second parts are inserted into a fixture such that at least one of the first and second parts engages the fixture. The fixture is heated with at least one electrical heating element to heat the filler metal by thermal conduction above a melting point of the filler metal and form metallurgical bonds between the filler metal and the first and second parts. The melted filler metal is cooled to join the first and second parts together.
