Coated foils are used in the creation of batteries, which have many applications, which we use day to day (e.g. mobile phones and laptops) as well in e-mobility. The foils are usually made of a highly conductive material such as copper or aluminium (or maybe even gold in mission-critical applications). These foils are also coated with a carbon-based material and with lithium-based oxides present on the cathodes. This makes the foils much more challenging to cut, which is why fiber lasers are ideal for this application. Read more about battery foil cutting, by reading our detailed guide.

Electric motor components production

As we wrote in our previous application insight – laser cutting in the automotive industry, there are numerous existing laser cut motor components in existing ICE vehicle models. These include airbags, automotive carriage components and hydroformed parts. These parts will continue to be laser cut in electric models too. The overall number of electric vehicle components is likely to reduce though as they require far fewer parts. Tesla has reported that “Our drivetrain has about 17 moving parts compared with about 200 in a conventional internal combustion drivetrain”. Source: Marketwatch.

Cutting stator plates in electric motors

The stator is an integral part of an electric motor, it is the part, which remains stationary. The stator is a steel frame and encloses a hollow cylindrical core. Using fiber lasers the stator plates can be cut to high levels of precision to the exact specification needed all through a non-contact process, which is error-free and highly repeatable, which makes it ideal for manufacturing processes. Read more about laser cutting of stator plates in our detailed guide.

Precision Cutting Applications for e-mobility

E-mobility is a major trend in automotive and many other industries. Lasers are already very actively involved in vehicle and parts production and this trend will continue with the switch from Internal combustion engine (ICE) models to electric vehicles and hybrids. One of numerous laser applications used by manufacturers is laser cutting, we discuss here some of the precision cutting applications for e-mobility.
