1. A turbomachine comprising a housing, a circuit assembly and a stator assembly, wherein:
the housing comprises an inlet for admitting a working airflow and a flange that extends from the inlet, the inlet overlying the stator assembly such that the stator assembly is visible through the inlet, the circuit assembly comprises a circuit board and an electrical component having a heat sink, and the circuit assembly is located within the housing such that the flange extends beyond the circuit board and the heat sink extends beyond the flange, wherein: the circuit board lies along a plane orthogonal to an axis of rotation of a rotor, and the plane is located at a first elevation on the axis of rotation of the rotor; the flange extends axially through the circuit board at least from the first elevation down to a second elevation on the axis; the electrical component and the heat sink extend axially from the first elevation down to a third elevation on the axis that is lower than the second elevation on the axis; the stator assembly extends from a fourth elevation along the axis to a fifth elevation on the axis; and a portion of the axis between the fourth elevation and the fifth elevation overlaps with a portion of the axis between the first elevation and the third elevation. |
