Abstract
An auto-focusing camera includes a stator (), a rotor () rotatably disposed in the stator, and a lens unit () received in the rotor. The stator includes a stator core () and coils () winding on the stator core. The rotor is a permanent magnet () securely mounted around the lens unit. The lens unit forms three ears () at a bottom thereof, and a wave-shaped surface () is formed on a top of an inner, bottom flange () of the stator. The ears abut the wave-shaped surface. The ears of the lens unit move along the wave-shaped surface during rotation of the rotor and the lens mount, and thus the lens unit moves telescopically along an axial direction thereof.
