The fundamental construction of electrical machines with arrangement of coilings on pole shoes has not changed for decades. The machines have, depending on their utilization as generators or motors, a limited efficiency and/or a limited torque and a limited performance/mass ratio. A design is being proposed where the stator and/or the rotor consists of a ring core (1) made of magnetically conducive material having areas acting as magnetic poles (4), recesses (2) in equal distribution or meander-shaped protruding and/or retreating areas (7) in radial direction, into which coil sections (3) of at least one coil are wound over an axis lying in the peripheral direction of stator and/or rotor and where the distances between the inversely poled permanent magnets (5) producing the exciting field or the electrically excited poles essentially correspond to the size of the interpolar gaps in stator and/or rotor. The machine has a substantially improved performance/mass ratio.
