The invention relates to an electrical machine of the transversal-flux type. The machine comprises a stator and a movable element. The stator has a plurality of stator elements with magnetic flux conductors and an electric winding extending in a closed winding path through each magnetic flux conductor. The movable element comprises a number of permanent-magnet members and is movable in relation to the stator along a movement path. The winding path comprises a first current-carrying section extending along the movement path. Each magnetic flux conductor forms, together with one of the permanent-magnet members, a closed magnetic flux circuit around said current-carrying section. Each permanent-magnet member comprises a primary magnet with a magnetic direction across the movement path. Adjacently located permanent-magnet members are separated from each other by an intermediate member comprising at least one secondary magnet that has a magnetic direction essentially across the magnetic direction of the primary magnet.

Electrical machine and use thereof

A hybrid drive device comprises an internal combustion engine and an energy converter adapted to co-operate with an output shaft of the internal combustion engine and which comprises an electric machine. The electric machine includes a first rotor connected to the output shaft of the internal combustion engine and a second rotor connected to a drive shaft. The two rotors are arranged with surfaces for co-operation by transmitting power through magnetism directed substantially in the direction of the axis of rotation of the rotors for substantially axial magnetic flux between the rotors.

Hybrid drive device

A device that includes a combustion engine with a piston that is mechanically freely movable in a housing. The device permits combustion of a fuel mixture to produce a pushing force to the piston. The device includes an electromagnetic energy transducer and an external current circuit, which is connected to the energy transducer for exchange of effect in a direction to or from the energy transducer. A control unit controls the direction of the effect, which is exchanged between the energy transducer and the external current circuit, during operation of the device. Such a device can be used to generate electrical energy, and can be employed in a vehicle.

Device including a combustion engine, a use of the device, and a vehicle

An electrical machine with at least a machine unit. This machine unit includes a stator, which includes a plurality of magnetic flux conductors, an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and a least one first movable element, which includes a number of permanent magnet elements and which is movable in a reciprocating movement in relation to the stator along a first movement path in a space having a finite length and formed by at least some of the magnetic flux conductors. The winding path includes a first current carrying portion, which extends substantially in parallel with the first movement path. Each magnetic flux conductor is arranged to form, together with one of the permanent magnetic elements, a closed magnetic flux circuit extending around the current carrying portion.
