<p>To provide an accessory drive system which is capable of achieving downsizing of the system, reduction of manufacturing costs thereof, and enhancement of its marketability. An accessory drive system 1 is comprised of a stator 6, a first rotor 5, and a second rotor 7, which include a plurality of armatures 6a, permanent magnets 5a, and first and second cores 7a and 7b, all of which are arranged in a circumferential direction, respectively. One of the first and second rotors 5 and 7 is connected to an accessory 22, and the other to an internal combustion engine 21. Further, when the polarity of a first armature magnetic pole of each armature 6a is different from the polarity of a first magnetic pole of an opposed one of the permanent magnets 5a, the polarity of a second armature magnetic pole of the armature 6a becomes the same as the polarity of a second magnetic pole of the opposed one of the permanent magnets 5a. Further, when a first core 7a is in a position between a first magnetic pole and a first armature magnetic pole, a second core 7b is in a position between two pairs of second armature magnetic poles and second magnetic poles circumferentially adjacent to each other.</p> |
