Provided are a conveying device and a conveying method capable of detecting a speed of a conveyed object more accurately than that in the related art. The conveying device includes a coil 107 that includes a core 105 and a winding 106, a current detection unit 109 that detects a current flowing through the winding 106 of the coil 107, a drive unit 108 that supplies a voltage to the coil 107, and a control unit 110. The control unit 110 estimates a conveying speed of a holder 102 provided with a magnetic body 103 based on the current flowing through one winding 106 due to an influence of electromagnetic induction.

Velocity detection is the crucial step for motion feedback and control. A dynamic loudspeaker can be conceptualized as a motion conductor within magnetic field. This invention calculates the velocity of a motion conductor, uses operational amplifier to emulate the calculation and realize the velocity detection.
