PURPOSE: A ripple force correcting device, a linear motor, and a ripple force correcting method are provided to accurately move an electronic part to a mounting position on a PCB by stably moving an absorbing nozzle for absorbing the electronic part to a fixed position. CONSTITUTION: A ripple force correcting device(300) includes a storage part and a correcting part. A ripple force data composed of a current value due to a moving position is stored to the storage part(310). The correcting part(320) linearly corrects the ripple force data. The correcting part linearly corrects the ripple force data by synthesizing the ripple force data to the corrected ripple force data. |
