A voice coil motor includes a stationary magnetic field generator a moveable magnetic field generator, and an elastic assembly. The stationary magnetic field generator includes a supporting frame and permanent magnetic elements mounted to peripheral sides of the supporting frame. The supporting frame has a first receiving space defined therein and includes first stopping portions formed in the first receiving space. The moveable magnetic field generator is moveably received in the first receiving space, and includes a core member and a coil wrapped around the core member. The core member includes second stopping portions. The second stopping portions are configured for engaging with the at least one first stopping portion to prevent the moveable magnetic field generator from rotating about a central axis of the core member. The elastic assembly elastically connects the moveable magnetic field generator and the stationary magnetic field generator.
