<P>PROBLEM TO BE SOLVED: To provide an angle detector capable of easily automating wire winding, while easily reducing size and cost even in a resolver or a synchro device with a large shaft angle multiplier. <P>SOLUTION: When taking an amplitude modulating resolver of a shaft angle multiplier 32X for example, the number of winding grooves 2 of a stator core 1 is set to 16 pieces which are less than twice the shaft angle multiplier, and the number of winding grooves 5 of a rotor core 4 is set to 64 which is twice the shaft angle multiplier as commonly practiced. One or more small teeth 31 are arranged on each tooth 3 of the winding grooves 2. In this example, the number of small teeth is arranged by two, and the total number of the small teeth 31 is set in the number equal to the shaft angle multiplier 32X. <P>COPYRIGHT: (C)2009,JPO&INPIT |
