Abstract:
A VCM (voice coil motor) is disclosed, the VCM including: a rotor including a lens-fixing hollow holed bobbin including a coil discharge unit formed from a peripheral upper end to a peripheral bottom end facing the peripheral upper end, and a coil block arranged at a periphery of the bobbin and including a cylindrically wound coil; a stator including a magnet facing the coil block and a yoke fixing the magnet; a case including a bottom case arrange with the bobbin and an upper case coupled to the bottom case and having an opening at a portion corresponding the bobbin; and an elastic member elastically supporting an upper end of the bobbin and a bottom end facing the upper end of the bobbin, wherein a distal end of the coil arranged at an upper end of the coil block employs the coil discharge unit to be discharged to a bottom end of the bobbin.
