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.

Abstract: A driving apparatus comprises a stator (21), a rotor (22) and a deformation connector (23). The rotor is connected to the stator through the deformation connector. An external driving force drives the deformation connector to have deformation so that the rotor changes its position with respect to the stator. Under the condition that no external driving force is applied, the deformation connector remains at a force balanced position (x0). The force on the deformation connector comprises a deformation force (F1) of the deformation connector and a first primitive force (F2) in opposite direction to the deformation force (F1). Also provided is a device fabrication method. Because the deformation connector keeps balance under the effect of the deformation force and the first primitive force, a small external driving force is required when the driving apparatus operates near the balance point, hereby reducing power consumption.

Abstract: An electromagnetic motor is provided, which may include a stator (11) and a mover (12). One or both of the stator and the mover may be provided with windings. At least one of the windings is made of printed circuit (13). Because of the use of the printed circuit as windings, not only the working hours for forming the windings by copper wires and the copper material are saved, but also accurate circuit design can be achieved, which facilitates the miniaturization of the electromagnetic motor.

Abstract: A zoom/focus apparatus and corresponding zoom lens assembly are provided. The zoom/focus apparatus may include a first focus lens barrel (101), a first zoom lens barrel (102), a first ultrasonic motor and a second ultrasonic motor which are disposed coaxially. The first focus lens barrel and the first zoom lens barrel are radially unmovable. The caliber of the first zoom lens barrel is larger than that of the first focus lens barrel. The two ultrasonic motors are used to drive the two lens barrels to move axially by the rotation of the rotors (103, 104), respectively. Because the zoom lens barrel which needs to be moved is disposed at outside of the focus lens barrel, by driving the lens barrels using the ultrasonic motors, the telescoping of the zoom lens barrel and the adjusting of the zoom position can be achieved simultaneously.
