Abstract
A lift fan includes a stator which is configured to output a magnetic field. The lift fan also includes a first housing which in turn includes a blade, a second housing, and a magnet array. The magnet array is coupled to either the first housing or the second housing and the housing, which is coupled to the magnet array, rotates in response to the magnet array responding magnetically to the magnetic field output by the stator.
Claims19
A lift fan, comprising:
- a stator which is configured to output a magnetic field;
- a first housing which includes a curved surface, a flat surface, and an unshielded blade which extends radially outwards;
- a second housing which includes a curved surface and a flat surface, wherein the first housing and the second housing are incorporated into the lift fan such that the flat surface of the second housing faces the flat surface of the first housing and the curved surface of the first housing and the curved surface of the second housing are both exposed, wherein the first housing and the second housing are connected at a plurality of points to stabilize the lift fan during operation;
- and
- a magnet array, wherein:
- the magnet array is coupled to at least one of the first housing or the second housing;
- and
- the at least one of the first housing or the second housing which is coupled to the magnet array rotates in response to the magnet array responding magnetically to the magnetic field output by the stator.

A method, comprising:
- outputting a magnetic field using a stator, wherein the stator is included in a lift fan which further includes:
- a first housing which includes a curved surface, a flat surface, and an unshielded blade which extends radially outwards;
- a second housing which includes a curved surface and a flat surface, wherein the first housing and the second housing are incorporated into the lift fan such that the flat surface of the second housing faces the flat surface of the first housing and the curved surface of the first housing and the curved surface of the second housing are both exposed, wherein the first housing and the second housing are connected at a plurality of points to stabilize the lift fan during operation;
- and
- a magnet array, wherein the magnet array is coupled to the first housing or the second housing;
- and
- rotating the at least one of the first housing or the second housing which is coupled to the magnet array in response to the magnet array responding magnetically to the magnetic field output by the stator.
