A generator arranged to be driven by an aircraft engine, the generator comprising a stator and a rotor. The stator comprises a stator core and a plurality of slots longitudinally extending in a direction of a longitudinal axis of the stator, for receiving conductors to form windings of the stator, and a plurality of power channels. Each power channel comprises a set of windings having at least a first phase winding including a first set of coils comprising a plurality of conductors wound in a lap winding configuration, the first set of coils having a split phase belt such that the first set of coils comprises at least a first coil and a second coil, the first coil being mechanically shifted with respect to the second coil by a predetermined number of slots of the stator. The rotor comprises a permanent magnet adapted to reduce eddy-current losses.
