Busbar, Stator & Rotor
Over 25 Years of Expertise in Electromagnetic Core Assembly and Power Routing
The efficiency of an electric motor depends entirely on the seamless integration of its inner core and power distribution. Eckerle has over 25 years of experience in processing lamination stacks, permanent magnets, and complex busbars into highly efficient, ready-to-assemble motor systems. We bridge the gap between metal processing, magnetics, and precise insulation molding.
A special feature: We not only develop and produce the products themselves but also the automated and semi-automated production lines needed for manufacturing, all in-house.
Technology & Design That Drive Performance
Function of Integrated Motor Components
As the primary driving and power-routing elements of electric motors, stators, rotors, and busbars must withstand extreme rotational forces and thermal loads.
Eckerle provides a fully integrated solution: from specialized overmolding for lamination stacks and magnet insertion to custom-shaped 3D busbars that replace bulky cable harnesses. This unified approach minimizes tolerances, reduces energy loss, and optimizes electromagnetic compatibility (EMC).
