摘要：
A pump includes a housing, a stator supported in the housing, and a rotor assembly including a rotor supported in the housing for rotation relative to the stator about an axis. The stator includes a stator core, a first lamination wound around an axial portion of the stator core, and a second lamination wound around a second axial portion of the stator core. The first and second laminations are spaced from each other along the length of the stator core. The rotor includes a rotor core, a first magnet assembly that extends around an axial portion of the rotor core, and a second magnet assembly that extends around a second axial portion of the rotor core. The first and second magnet assemblies are spaced from each other along the length of the rotor.
