DRIVING DEVICE FOR REEL BASE

摘要

PURPOSE:To reduce a variation in torque by controlling the output torque of a motor in accordance with the deviation between a torque set value and the output in a pressure detector detecting the reaction force of a driving torque installed at the case of the motor. CONSTITUTION:A pressure detector 20 is installed at the case of a motor 21 and a motor 21 detects the reaction force arriving at a reel base 25 during torque transmission. A comparator 23 supplies the motor 21 with a deviation signal between the output signal in the pressure detector 20 and that in a torque setting device 22 through an amplifier 24. In this way, constant torque control without a variation in torque can be performed.
