<P>PROBLEM TO BE SOLVED: To provide a resolver which is capable of maintaining high accuracy even when an exciting coil plate or a detecting coil plate itself is transformed into waving or the like in a circumference direction. <P>SOLUTION: A resolver is characterized in that (a) a SIN signal detecting coil 10 is bisected in a circumference direction and also bisected in a diameter direction, a SIN first coil 11 and a SIN second coil 12 are disposed at an outer circumferential side, and a SIN third coil 13 and a SIN fourth coil 14 are disposed at an inner circumferential side, (b) the SIN first coil 11 and the SIN third coil 13 are disposed while being opposed to each other in the circumference direction and the SIN second coil 12 and the SIN fourth coil 14 are disposed while being opposed to each other in the circumference direction, and (c) the SIN first coil 11 and the SIN fourth coil 14 are disposed in a first coil layer 5 and the SIN second coil 12 and the SIN third coil 13 are disposed in a second coil layer 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
