摘要： An alternator for vehicle includes a stator that outputs an AC voltage and a rotor that includes a field coil and a rotor core. The stator includes a plurality of phase stators that are disposed side-by-side along the rotational axis and individually output AC voltages. The phase stators include an even number of stator tabs alternately extending from one outer side of a phase stator coil toward another outer side of the phase stator coil and extending from the other outer side toward the one outer side along the rotational axis. The rotor includes a field coil and a rotor core at which an even number of rotor tabs are formed along the circumferential direction so as to alternately extend from one outer side of the field coil toward another outer side of the field coil along the rotational axis and extend from the other outer side toward the one outer side along the rotational axis. A phase stator core at each phase stator is formed by laminating a plurality of magnetic sheets.

摘要： An efficient and high-performance commutator motor in which both torque enhancement and iron loss reduction are achieved is provided by ensuring a sufficient area occupied by field windings wound on main poles and further suppressing the influence of armature counteractive magnetic flux and reducing pulsating torque. The commutator motor includes a stator and an armature. The stator includes a stator iron core having the main poles and slots and the field windings disposed in the slots. The armature includes an armature iron core having slots and teeth and armature windings wound in the slots. The stator and armature iron cores are formed of laminated steel sheets. The iron cores are formed by etching process. Multiple through holes are formed in the main poles opposed to the air gap positioned on the forward side in the direction of armature rotation by etching process.

摘要： It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.
