Abstract

In a brushless synchronous machine with axial air gap and comprising a disc rotor 14 carrying permanent magnet segments 15, and two annular laminated stator cores 19, 20 which are held on both sides of the disc rotor 14 in the machine housing 10 and which in each case carry a three-phase armature winding 23, 24 wound of insulated wire, each laminated stator core 19, 20 is constructed as slotless sheet-steel coil 21, 22 of steel tape and each armature winding 23, 24 is constructed as self-supporting two- layer wave winding for the purpose of eliminating interfering detent torques and magnet tooth noises and of facilitating production. The armature windings 23, 24 are bonded to the face of the respective associated sheet-steel coil 21 or 22 by means of a casting compound.
