    摘要: A method of deriving a thrust constant representing an occurrence rate of a thrust in relation to a current in a linear motor which includes a magnet extending in a movement direction, and a moving body which includes a coil mounted to a track member in a movable manner, the linear motor generating a thrust in the movement direction between the magnet and the coil by causing the current to flow in the coil, in which an average thrust constant which is an average thrust constant in a long movement zone on the track member is derived based on actual measurement, local thrust constants which are local thrust constants of a plurality of locations on the track member are derived based on each actual measurement, and the thrust constants are derived based on the average thrust constant and the local thrust constant of each location.
