Abstract
PURPOSE: To obtain a detector of a sound installation condition of a detecting coil by winding a belt shaped detecting coil facing against to magnetic poles of a cylindrical shaped magnet upon an internal ring external peripheral surface of a supporter and by leading terminals out of an external peripheral ring outside of the supporter.
CONSTITUTION: At an internal peripheral surface of a cylindrical shaped rotor magnet 1, n poles magnetic pole train for a rotor driving and at an external peripheral surface m(m>n) poles magnetic pole train are magnetized and a detecting coil 5 of a ring shape is disposed for m poles magnetic pole train. This detecting coil 5 formed by wave shaped conductor layers 11 upon a flexible belt shaped insulating sheet 10 is adhered to an external peripheral surface of an internal peripheral ring 6B of a supporter 6 which has a double construction of an external peripheral ring 6A made from a non-magnetic body and an internal peripheral ring 6B and is maintained as a shape of a ring form. And a tongue piece portion 10A for an output terminal provided at both ends of the detecting coil 5 is led outside from a concavity 12 provided upon an external peripheral ring 6A and soldered to connecting pins 14A,14B.
