Electric machine e.g. permanent magnet synchronous machine, has stator units supported at stator carrier, where stator carrier and stator units are penetrated through shaft, rotor unit secured at ends of shaft, and pump arranged in carrier

摘要

The machine has two axially spaced-apart mutually aligned stator units (2, 3) associated with rotor units (4, 5) e.g. external rotors, where the rotor units are connected together. The stator units are supported at a central stator carrier (1) with respect to axial extension of the central stator carrier. The stator carrier and the stator units are penetrated through a rotatably mounted rotor shaft (6), and one of the rotor units is secured at ends of the shaft. A pump (7) e.g. annular gear pump, is arranged in the stator carrier and attached to a hydraulic system.
