Abstract
The present invention relates to a magnetic flux conducting unit (10) for electromagnetic apparatus, the electromagnetic apparatus being operative to convert one of mechanical energy and electrical energy into the other of mechanical energy and electrical energy. The magnetic flux conducting unit comprises at least one magnetic flux conducting element (12a, 12b) formed of a magnetically permeable material. Also, the at least one magnetic flux conducting element defines: a coil receiving space (18) for receiving a coil assembly (32) of the electromagnetic apparatus; and at least one material receiving space (16, 30a, 30b), which accommodates a substantially magnetically impermeable material.
