A method for producing a component for an electric machine from a laminated core, which includes multiple grooves and a central axis, and a plurality of wire elements. Each wire element includes two legs made of wire, which are or will be connected to one another via a bend made of wire. At least the legs of the wire elements are arranged in parallel to the axis in the grooves. A temperature sensor is fastened at a bend of at least one wire element.

An aligning apparatus, which is provided for aligning coil segments to form an aligned coil, includes a cylindrical jig and a hook jig. The cylindrical jig has an outer cylinder to surround a radially outer periphery of the aligned coil and an inner cylinder to be surrounded by a radially inner periphery of the aligned coil. The hook jig has hooks arranged in a radial fashion and is rotatable relative to the cylindrical jig in a radial direction. The cylindrical jig further has an inner entrance provided in the inner cylinder, an outer entrance provided in the outer cylinder, and at least one of an inner guide wall extending from a front opening edge of the inner entrance radially inward and backward in the rotational direction and an outer guide wall extending from a front opening edge of the outer entrance radially outward and backward in the rotational direction.
