Electric generator device

An electric generator device (20) comprising:

• at least one rotor (22) having an axis of rotation (22c) and comprising one or more magnetic elements (22b) disposed around the axis of rotation (22c) on the rotor yoke (22a), the one or more magnetic elements (22b) defining pole pairs adapted to create an alternating magnetic field when rotated around the axis of rotation (22c);
• at least one coil (26), having a central axis (26a), said at least one coil (26) being remote from said at least one rotor (22) such that the coil is located non-coaxial with, offset from or away from a direct influence of the alternating magnetic field such that central axis (26a) is outside an envelope of the rotor, and
• a magnetic or ferromagnetic bridge, comprising at least a first and second bridge elements (24a, 24b) joining said at least one rotor (22) to said at least one coil (26), said at least first and second bridge elements (24a, 24b) comprising couplers in form of protrusions or teeth (24c) in the vicinity of and located to encircle said one or more magnetic elements (22b) so that a voltage within the at least one coil (26) is induced due to the alternating magnetic field within said magnetic or ferromagnetic bridge (24a, 24b) caused by the rotation of the one or more magnetic elements (22b) around the axis of rotation (22c), wherein
• the protrusions or teeth (24c) are interdigitated between both halves of the magnetic or ferromagnetic bridge (24a, 24b) and a total number of the protrusions or teeth (24c) corresponds to double the number of pole pairs defined by the one or more magnetic elements (22b).
