A grinding mill comprising
- a stator comprising a bore therethrough, said stator further comprising a plurality of substantially identical linear stator portions, each stator portion comprising one three phase winding and a linear drive, each said three phase winding comprising an even number of poles and substantially galvanically isolated from other said three phase windings, one said linear drive comprising a master drive and controlling all other said drives;
- a shell rotatably mounted at least partially within said bore;
- and
- at least one winding mounted on said shell separated from said stator by an air gap.
