PROBLEM TO BE SOLVED: To provide an electromagnetic transducer capable of magnetizing it in a state such that a rotor magnet consisting of heterogeneous magnet is installed in the device together with a gear train, preventing lack of magnetizing and the failure of rotor shaft and the like and improving productivity. SOLUTION: A device is constituted to be capable of loosening a rotor 31 and a gear 26 with an electromagnetic transducer in the state the rotor 31 is supported by a support member 42. Therefore, the effect of inertia from the gear 26 to the rotor 31 in magnetizing is eliminated, and the rotor can be magnetized by avoiding lack of magnetizing and a failure of the rotor shaft 31c in the state the rotor 31 installed in the device together with a gear train. Furthermore, only one kind of coil of detaching in magnetizing and so the recycle time of assembling can be shortened and productivity of electromagnetic transducer can be improved. |
