<P>PROBLEM TO BE SOLVED: To provide a control system for a welding motor for a strapping machine in accordance with the number of rotations of the weld motor. <P>SOLUTION: The control system is for a strapping machine of a type having a body section, an anvil movably mounted to the body section, a seal member disposed so as to perform an oscillating movement on the anvil and a motor movably connected with the seal member so as to provide the oscillating movement to the seal member. Since the control system counts a sensing object factor (32) disposed at the rotating section of the motor, a sensor (30) which transmits a signal every time the sensing object factor is sensed and the number that the sensing object factor (32) is sensed, it has a counter (36) movably connected with the sensor (30) and a controller which controls the operation of the motor (12) in accordance with the number that the sensing object factor (32) is sensed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
