[OBJECT] PREVENT PROBLEMS FROM BEING PRODUCED IN EXTERNAL DEVICES THAT ARE LOCATED NEAR A MOTOR CONTROLLER OF A MOTOR DRIVEN REEL. [MEANS OF SOLUTION] A MOTOR OF A MOTOR DRIVEN REEL INCLUDES A NOISE REDUCTION VARISTOR (66) CONNECTED THERETO. THE VARISTOR (66) FORMS A PART OF THE MOTOR (12), AND IS CONNECTED IN PARALLEL WITH THE TERMINALS OF THE MOTOR (12). A PWM DRIVE CIRCUIT (45) THAT PWM DRIVES THE MOTOR (12) IS CONNECTED TO A NOISE REDUCING CHOKE COIL (45). THE CHOKE COIL (65) IS PROVIDED IN THE PWM DRIVE CIRCUIT (45), AND IS CONNECTED IN PARALLEL WITH THE MOTOR (12). THE CHOKE COIL (65) AND THE VARISTOR (66) ARE NOISE REDUCTION ELEMENTS THAT REDUCES THE NOISE OF THE MOTOR (12).FIG.5
