A zoom lens driving device and a zoom lens. The driving device comprises a focus motor (402) and a zoom motor (403) that are respectively used for driving a first focus lens group (411) and a first zoom lens group (414) to move axially. At least one of the focus motor and the zoom motor is a disc-type electromagnetic motor in which a stator (410) and a rotor (403) have a hollow structure. The disc-type electromagnetic motor having a hollow structure is used as the lens driving motor, is easy to process, and is easy to be combined with another motor, for example, another disc-type electromagnetic motor or voice coil motor or ultrasonic motor to form a compact structure, thereby meeting the requirements of zoom lens of micro to large sizes. |
