Abstract
A reluctance machine includes a stator having an annular support member with a plurality of stator poles disposed thereon. The stator poles each are formed from a corresponding foil coil stator winding. A solid disc-shaped rotor defines a plurality of salient rotor poles, and is rotatably positioned opposite the support member to establish an axial air gap between the rotor and stator poles. A food waste disposer incorporates such a reluctance machine.
Claims47
A food waste disposer comprising:
- an inlet for receiving food waste;
- a grinding plate coupled to a rotatable shaft for grinding the food waste;
- and
- a switched reluctance motor operable to drive the shaft.

A food waste disposer comprising:
- an inlet for receiving food waste;
- a motor comprising
- a stator having a central axis and including windings, and
- a rotor having rotor poles extending radially from the central axis and over the windings, wherein the rotor poles are spaced from the windings by an air gap, and wherein no structure of the food waste disposer appears in the air gap between the rotor poles and the windings;
- and
- a grinding plate coupled to the rotor for grinding the food waste.
