An angle detector with a shaft angle multiplier of 32X shown in Fig. 2 is structured so that the number of winding grooves (2) of a stator core (1) is sixteen which is less than twice the shaft angle multiplier and so that the number of winding grooves (5) of a rotor core (4) is sixty four which is twice the shaft angle multiplier as commonly practiced. One or more small teeth (31) are formed on each tooth (3) of the winding grooves (2). In one embodiment, the number of the small teeth (31) is two for each tooth (3); therefore, the total number of the small teeth (31) is equal to the shaft angle multiplier of 32X. Consequently, even a resolver or a synchro with a large shaft angle multiplier can be easily reduced in size and cost, and wire winding is easily automated. |
