Abstract
The present disclosure provides a linear driving apparatus. The linear driving apparatus includes: stators; rotors slidably arranged on the stators; a driving component configured to drive the rotors to slide along an extension direction of the stators; first position feedback units provided with one first position feedback unit provided with a marking signal; and second position feedback units arranged on the stators and spaced apart. The second position feedback units is configured to read position information of the first position feedback units and read the marking signal. The linear driving apparatus in the present disclosure can simplify a manner of identifying the rotor without additional sensors, thereby reducing costs.
