Components
Wieland components for better electric motors and higher-efficiency batteries. The challenge to optimise the key element battery for electromobility provided the idea of enhancing the efficiency of all components – from the rotor to the wiring to the drivetrain. As a partner of many years’ standing to the automotive industry, Wieland utilises its unique, broadfronted access to key technologies to develop high tech components for electromobility.
This includes rotors for maximised electrical power to contacting components for stator windings in the tightest of spaces and precision resistors for ultra precise measurements. As a leading manufacturer of semifinished products of copper and copper alloys, including strips for plug connectors, semiconductor components, and electrical and electronic components, Wieland has proved its reliability as a services partner from prototyping to series production.
As a rule, these products are developed in a partnership with the most-highly renowned automotive manufacturers, testifying to the knowhow and position of Wieland on the market.

Components for asynchronous machines and permanently excited synchronous machines
Copper rotors
The Wieland copper rotor design for induction motors is a patented layout that can withstand rotary speeds considerably higher than the alternative solutions. Thanks to the high conductivity of copper, the rotor attains an efficiency higher than aluminium and is designed for mass production.
Rotor bars
Wieland can offer you ready-to-install rotor bars of the unvaryingly highest quality combined with maximum cost efficiency. This is safeguarded by our fully automated processes over the whole value creation stream – from development to production – from the smallest sample lot to mass production.
Wiring
Contacting your stator windings in the tightest of spaces – Together with you, we develop individual solutions for wiring your electrical machinery and produce these from the prototype to the series product. This also extends to hairpin windings that increase both the copper fill factor in the stator and the efficiency of the electrical machinery in EV and EHV drives.
Battery components
Shunts
Precision shunt resistors are highly important for the precise, reliable measurement of actual battery levels, first making possible better battery management. Shunt resistors are based on electron beam welded copper-manganese strip. This allows high precision measurements over a wide temperature range and provides the connection to the power electronics of the stator in the drivetrain.
Special bimetals
Special bimetals constitute an additional contribution towards improved battery design and are used as so called busbars between the anode and cathode. Laser deposit welding is a method developed specially for combining the properties of different metals into a composite with excellent contact bond strength. This method introduces high degrees of freedom to flexibility and dimensioning.
