摘要： A compact and reliable structure of a multi-rotor synchronous machine which may be employed as a generator/motor for automotive vehicles is provided. The machine includes an outer rotor having permanent magnets, an inner rotor having permanent magnets disposed to be rotatable relative to the outer rotor, a stator core having armature coils interlinking with field magnetic fluxes produced by the outer and inner rotors, and a rotor-to-rotor relative rotation controlling mechanism. A relative angle between the outer and inner rotors is controlled within a given angular range by controlling the phase and quantity of current flowing through the armature coils to rotate the inner rotor relative to the outer rotor through the rotor-to-rotor relative rotation controlling mechanism, thereby changing the magnetic fluxes interlinking with the armature coils as needed.

摘要： Pole core members of a rotor are fitted on a rotary shaft with claw-shaped magnetic poles engaged with one another from front and rear sides. Each of magnet mounting members for holding magnets against side surfaces of each magnetic pole has magnet retaining portions on both sides and a platelike middle portion. Located between two adjacent claw-shaped magnetic poles, each magnet produces a magnetic field oriented in a direction opposite to the direction of a magnetic flux formed between the adjacent claw-shaped magnetic poles. The claw-shaped magnetic pole has a stopper portion at its extreme end on an inclined inside surface. The magnet mounting member carrying the magnets in the magnet retaining portions is mounted on each claw-shaped magnetic pole with the middle portion of the magnet mounting member situated against the inclined inside surface of the magnetic pole, and a backup ring is fitted inside the magnet mounting members.

摘要： A high-speed rotor, in particular a permanent-magnet rotor (1) for dynamoelectric machines of high power density, and also its production are proposed. The permanent-magnet rotor (1) comprises a spindle (2) and armouring (4) coaxial with the spindle (2), a number of ceramic permanent magnets (3a-3d) that are distributed between the spindle (2) and the cylindrical sheath (4), and also a gap-filling filling compound. Said filling compound made of filled polymers seals the gaps in the permanent-magnet rotor (1) by injection moulding. Due to the remanent pretension, the permanent magnets (3a-3d) remain permanently rigidly joined even against high centrifugal forces.
