PROBLEM TO BE SOLVED: To obtain a small-sized inexpensive motor by erectly mounting a second substrate mounted with a magnetoresistive element, which outputs a rotating speed signal on a first substrate holding a drive coil. SOLUTION: A rotating speed detecting magnet 4 is attached to the outer periphery of a rotor 3 rotatably faced to a drive coil 2 fixed on a first substrate 1 and a second substrate 9 fitted with a magnetoresistive elements 5 is erectly mounted on the first substrate 1 and electrically connected to the first substrate 1 by soldering. Therefore, a small-sized inexpensive capstan motor can be realized, because a space occupied by the magnetoresistive element 5 on a stator substrate and the number of parts can be reduced. |
