A stage apparatus is provided. The stage apparatus includes: a first stage; a first actuator configured to drive the first stage; a second stage supported by the first stage; a second actuator configured to contactlessly transmit a thrust applied to the first stage by the first actuator to the second stage; a driver configured to drive the second actuator; and a controller configured to control the first actuator and the driver. In a case of applying an electric brake to the first stage by using the first actuator, the controller is configured to apply the electric brake after a lapse of a predetermined time since output of control signal for controlling the second actuator from the driver is stopped.
A stage apparatus comprising:
A method of driving a stage apparatus, the stage apparatus including a first stage, a first actuator configured to drive the first stage, a second stage supported by the first stage, a second actuator configured to contactlessly transmit a thrust applied to the first stage by the first actuator to the second stage, and a driver configured to drive the second actuator,
