motorkärnor

Motorkärnor, often translated as motor cores or engine cores, refers to the essential components that form the heart of an electric motor. These cores are typically made from laminated sheets of ferromagnetic material, such as silicon steel. The lamination is crucial to reduce energy losses caused by eddy currents, which are induced within the conductive core material by the changing magnetic fields.

The motor core consists of two main parts: the stator core and the rotor core. The stator core is the stationary part of the motor and houses the windings that generate the rotating magnetic field. The rotor core is the rotating part and is responsible for producing the motor's output torque. The design and material properties of these cores significantly influence the motor's efficiency, power density, and performance characteristics. Advanced materials and manufacturing techniques are continuously being developed to improve the magnetic properties and reduce losses in motorkärnor, leading to more efficient and powerful electric motors.
