摘要： An electronically commutated electric motor is disclosed with a stator, a rotor rotatably mounted relative to the stator, and at least one sensor for scanning a magnetic field that co-rotates with the rotor, where the stator includes a stator winding and a magnetically soft stator core, where the rotor includes several permanent magnets arranged distributed in the circumferential direction of the rotor as well as a first magnetically soft rotor core for the permanent magnets, and where the permanent magnets, together with the first magnetically soft rotor core, generate a rotor magnetic field which, for operating the electric motor, interacts with the stator magnetic field of the stator generated by the stator winding and the stator core. A second magnetically soft rotor core adjoins the first magnetically soft rotor core in the axial direction of the rotor. A non-magnetic separator element is arranged in the axial direction, where the permanent magnets extend over the first magnetically soft rotor core, the non-magnetic separator element and the second magnetically soft rotor core.

摘要： A rotor for a small electric engine. The rotor having a rotor axis, multiple permanent magnets that are arranged in a spoke-shaped way as well as several inference cores. Each of the permanent magnets has two axial ends, two longitudinal sides, a radial outer side as well as a radial inner side. The inference cores protrude radially over the permanent magnets in relation to the rotor axis. The rotor is enclosed at least partially by a casting mold having multiple struts that extend in an axial direction and that overlap radially with the permanent magnets. The inference cores do not overlap with the permanent magnets on their radial outer sides, wherein both the permanent magnets as well as the inference cores are held together primarily directly by the casting mold in a radial direction.

摘要： An electronically commuted electric motor with a stator and a rotor is disclosed that has permanent magnets distributed a circumferential direction to determine the magnetic field of the rotor, whereby at least one sensor makes the position or speed of the rotor recordable through direct sampling of the magnetic field of the rotor. The sensor is spaced from the stator in a way that the stator field is recorded by the sensor only to a low extent or not at all, and whereby magnetic flux-guiding elements are disposed on a front side of the rotor, which move along with the rotor and guide at least a part of the magnetic field of the rotor to the sensor. The flux-guiding elements viewed in the circumferential direction of the rotor are positioned respectively between two permanent magnets of the rotor.
