Abstract: A power transmission apparatus working to magnetically transmit power is provided which includes a first rotor including n soft-magnetic members, a second rotor including k soft-magnetic members, and a third rotor including magnets whose number of pole pairs is m where m is an integer more than or equal to one, the number of the magnets meeting a relation of 2m=|k±n| where n and k are an integer more than one. The first rotor, the second rotor, and the third rotor are arranged in magnetic coupling with each other. The soft-magnetic members of each of the first rotor and the second rotor are arranged at intervals away from each other, thereby minimizing the leakage of magnetic flux flowing from one of the soft-magnetic members to another in each of the first and second rotor to ensure the stability in operation of the power transmission mechanism.

Abstract: A double drive shaft motor has a field rotor supported by a first rotating shaft, a magnetic induction rotor supported by a second rotating shaft, a stator supported by a motor housing casing, a first rotation limitation section arranged between the motor housing casing and the first rotating shaft, a magnetic bi-directional clutch arranged between the motor housing casing and the second rotating shaft, and a magnetic bi-directional clutch arranged between the first rotating shaft and the second rotating shaft. Each magnetic bi-directional clutch operates by receiving a rotational force supplied from the corresponding rotating shaft without using any outside energy to maintain a connection state of the corresponding rotating shaft. The first rotation limitation section is a one-way clutch without requiring any electric control. This makes it possible to make plural operation states, for example, eight operation states from an engine start to an EV drive of a vehicle.

Abstract: An AC excitation synchronous rotating electric machine includes a multi-phase coil, an armature core, an outer yoke core, a field-winding-less rotor and a controller. The armature core has the multi-phase coil wound thereon. The rotor is rotatably disposed so as to face the armature core and includes magnetic poles each having a facing portion and a magnetic reluctance portion. The facing portion is provided at one axial end of the magnetic pole so as to face the outer yoke core and allow magnetic flux to flow therebetween. The magnetic reluctance portion is provided at the other axial end of the magnetic pole to impede the magnetic flux from flowing therethrough. The controller controls supply of multi-phase alternating current to the multi-phase coil so that magnetomotive force generated in the armature core is applied to the magnetic poles, thereby causing the magnetic poles to operate as a DC field.

Abstract: A double-stator includes outer and inner stators each having magnetic poles. Outer-stator and inner-stator windings are connected in series in phases, thereby generating winding magnetomotive force. Outer magnets and inner magnets of a rotor are arranged in a rotor core in the circumferential direction, the outer and inner magnets being alternated between a radially outward portion and a radially inward portion, at a pitch equal to that of the poles of the outer and inner stators so as to be magnetized so that a radially outer side thereof will serve as N poles or S poles and that a radially inner side thereof will serve as S poles or N poles. The rotor core includes outer poles formed between the outer magnets circumferentially adjacent to each other in the radially outward portion, and inner poles formed between the inner magnets circumferentially adjacent to each other in the radially inward portion.

Abstract: A double-stator synchronous motor has a rotor, an inner stator and an outer stator. The rotor has segment-magnetic poles arranged in a ring shape. Magnetic poles formed in the inner stator and the outer stator face to each other in a same circumferential position. Each stator has q (q≧2) slots per pole and phase to disperse magnetomodive force. A radially minimum width Wr of each segment magnetic pole is within a range of 1.3q to 2.3q times of a minimum width Wt of outer teeth. A magnetic depth of a magnetic concave section formed in the segment magnetic pole is within a range of not less than an average width Ws of the inner slots. Because this suppresses demagnetization in the permanent magnets caused by stator magnetomotive force, ferrite magnets are used as buried magnets and magnetic-pole central magnets, and suppress the amount of neodymium magnet used in the rotor.
