<p>PROBLEM TO BE SOLVED: To provide a capstan motor for video tape recorder (VTR) which does not exert adverse effect upon a video signal on a VTR circuit board in which man-hour for IC assembly is reduced and costs can be reduced as well. SOLUTION: In a C motor 3 for VTR provided with a rotor 7 having a shaft 2 and a rotor yoke 1 fixing a driving magnet 10 and erecting the shaft, a motor base 19 overlapping a sheet metal 16 and a circuit board 17 and a stator 15 having a core 8 fixed on the motor base while winding a coil 9 and a bearing 22 for freely rotatably holding the shaft, a C motor driving circuit 26 for generating a driving current to be supplied to the C motor for VTR, a D motor driving circuit 27 for generating a driving current to be supplied to a D motor 4 for VTR and an L motor driving circuit 28 for generating a driving current to be supplied to an L motor 5 for VTR are packaged on the circuit board and respective motor driving circuit power sources are supplied from the outside of the circuit board.</p> |
