The present invention relates to an electrical machine including a rotor shaft, a hollow-cylindrical magnet element, a first covering disk, and a second covering disk, in which the first and second covering disks are secured to the rotor shaft, and the magnet element is secured on its first axial end to the first covering disk and on its second axial end to the second covering disk.

Rotor for an electrical machine with improved temperature stability

An electrical machine is described, having a stationary main element as stator and a rotating main element as rotor, of which one main element having a magnetic yoke and poles, of a predefined number of poles, projecting radially from the former, is made of SMC material and carries a pole winding on each pole. To achieve cost-effective manufacturing of the main element, the main element is assembled from at least two modules that are axially adjacent, rigidly connected to one another, and produced from SMC material, each module having a yoke part, closed in on itself, of the magnetic yoke having an equal number of divisions of poles attached thereto in one piece, which corresponds to a fraction of the number of poles determined by the number of modules.

Electrical machine

An electrical machine, in particular a brushless synchronous motor has a stator () and a rotor () with salient poles () disposed distributed over its circumference, each of which poles has an enclosed permanent magnet () and a pole shoe () that extends radially outward from the permanent magnet and defines an air gap () between the stator () and rotor (). In order to achieve a low cogging torque and a low torque undulation, the pole shoes () are embodied as magnetically anisotropic, with a preferred direction of the greater magnetic conductivity extending parallel to the radial salient pole axis.
