Abstract
A linear motor device includes a linear motor and a control unit configured to apply a load to a pressurizing object by causing a movable part of the linear motor to move. After causing the movable part to move toward the pressurizing object at a predetermined first speed based on position control, the control unit controls the movable part to move by performing deceleration to a second speed which is slower than the first speed and at which the pressure applied to the pressurizing object is less than or equal to a predetermined pressure when the movable part starts to apply the pressure to the pressurizing object, and the control unit causes the movable part to move until the current flowing through the linear motor is greater than or equal to a predetermined current limit value.
