Abstract: 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.

Abstract: An electrical machine with at least a machine unit. The machine unit includes a stator, which includes a plurality of magnetic flux conductors and an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and a movable element, which includes permanent magnet elements movable in a reciprocating movement in relation to the stator along a movement path. The winding path includes a first current carrying portion, which extends substantially in parallel with the movement path. Each magnetic flux conductor is arranged to form, together with one of the permanent magnet elements, a closed magnetic flux circuit extending around the current carrying portion. The magnetic flux conductors are arranged in an alternating order with respect to the direction of the magnetic flux in relation to the permanent magnet elements in the respective magnetic flux circuit.

Abstract: The invention refers to an electrical machine with at least a machine unit (1). The machine unit includes a stator, which includes a plurality of magnetic flux conductors (3′, 3″) and an electric conductor forming a winding extending in a substantially closed winding path through each magnetic flux conductor, and a movable element (10), which includes a number of permanent magnet elements (12′, 12″) and which is movable in a reciprocating movement in relation to the stator along a movement path. The winding path includes a first current carrying portion (6a), which extends substantially in parallel with the movement path. Each magnetic flux conductor (3′, 3″) is arranged to form, together with one of said permanent magnet elements (12′, 12″), a closed magnetic flux circuit extending around said current carrying portion.

Abstract: A hybrid drive system includes an internal combustion engine with an output shaft. An energy converter is connected to the output shaft via a coupling. The energy converter has first and second rotors which are rotatable at different speeds in relation to each other. At least one of the rotors is provided with one or more windings which are supplied with current from a current converter. The current converter is supplied with direct current from a direct current source. A transmission with variable gear ratio is coupled to one of the rotors. The transmission and the current converter cooperate via a control arrangement. The control arrangement comprises a control unit for controlling rotational speed and torque of the internal combustion engine and the energy converter.
