Abstract: There are provided an actuator driving apparatus, a camera module, and an electronic apparatus to selectively use a position and current control method and a current control method. The actuator driving apparatus includes a position controller and a current driver. The position controller is configured to receive a control input signal and output the control input signal or a position control signal, which is generated based on the control input signal, according to a mode signal. The current driver is configured to generate a current to drive an actuator according to the control input signal or the position control signal.

Abstract: Disclosed herein is a spindle motor. The spindle motor uses a general (non neodymium) permanent magnet rather than a neodymium magnet as a permanent magnet and compensates for a reduced counter electromotive force (B-EMF) value by allowing the center of a connection part formed in a round shape between poles around which coils are wound to be different from that of a core to increase a coil inductance value, thereby making it possible to easily sense and control a rotation state of the spindle motor.
