Abstract
A disc rotor for an electrical machine comprises a rotor body (1) of a temperature resistant polycrystalline sintered ceramic material which is insensitive to heat shock and a winding of bare metal conductors (2) applied to adhere firmly to both sides of the body (1) by direct eutectic bonding. The ceramic may be Al2O3, BeO or Si3N4, and the conductors may be copper or aluminium, in the latter case bonded by an Al/Si eutectic. <IMAGE>
