<P>PROBLEM TO BE SOLVED: To easily manufacture a rotor for dynamo-electric machine where the positional detection of the rotor at start or speed reduction becomes possible without being provided with a rotation sensor member. <P>SOLUTION: This rotor for permanent magnet type dynamo-electric machine, which includes a rotating shaft, a rotor core 2, and a plurality of permanent magnets 3 arranged at the peripheral face or the inner perimetrical face of the rotor core 2, is further equipped with one or more conductive circuits 5 which are constituted to surround the periphery of the plurality of permanent magnets 3 and in which a difference arises in inductance that is generated by an induced current that flows according to the rotational angle of the dynamo-electric machine. <P>COPYRIGHT: (C)2009,JPO&INPIT |
