Abstract
A method of manufacturing a component of an electric motor includes the steps of: applying a plurality of doses of adhesive to a first side of a metal sheet, wherein the adhesive is an acrylic adhesive that contains at least one of butadiene rubber toughener and polyurethane methacrylate; applying a plurality of doses of activator to a second side of the metal sheet opposite the first side; and cutting out a plurality of metal laminations from the metal sheet, each of which includes a dose of adhesive on the first side of the lamination and a dose of activator on the second side of the lamination, such that the plurality of metal laminations are stacked within a choke and each metal lamination is adhered to at least one adjacent metal lamination by the adhesive activated by the activator.

A method of manufacturing a component of an electric motor, comprising the steps of:
- applying a plurality of doses of adhesive to a first side of a metal sheet, wherein the adhesive is an acrylic adhesive that contains at least one of butadiene rubber toughener and polyurethane methacrylate;
- applying a plurality of doses of activator to a second side of the metal sheet opposite the first side;
- cutting out a plurality of metal laminations from the metal sheet, each of which includes a dose of adhesive on the first side of the lamination and a dose of activator on the second side of the lamination, such that the plurality of metal laminations are stacked within a choke and each metal lamination is adhered to at least one adjacent metal lamination by the adhesive activated by the activator;
- and
- curing the plurality of metal laminations within the choke to produce the component, and wherein the metal sheet is formed of a monolithic sheet metal such that each of the plurality of metal laminations is formed of a monolithic sheet metal.
