Abstract: An ultrasonic piezoelectric motor includes a frame, a carrier, and a Z-direction piezoelectric driver. The carrier is disposed on an inner side of the frame and moveable in a Z direction relative to the frame, the carrier is configured to receive a camera lens, and the Z direction is parallel to an optical axis of the camera lens. A Z-direction piezoelectric driver is located between the frame and the carrier. The ultrasonic piezoelectric motor periodically abuts against the carrier using the Z-direction piezoelectric driver and drives the carrier to move in the Z direction to focus a camera module.

Abstract: A camera system includes a module frame, a camera lens, an image sensor, and an SMA motor that are stacked within the module frame. The camera lens is fixedly connected to the module frame, and the SMA motor is located on an out-light side of the camera lens. The image sensor is located between the camera lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift in a direction parallel to an optical axis of the camera lens. The SMA motor is further configured to actuate the image sensor to shift on a plane perpendicular to the optical axis of the camera lens.

Abstract: Disclosed are a motor (20, 40, 50, 60, 70, 80), a camera module (100), and a mobile terminal (200). A motor (20, 40, 50, 60, 70, 80) includes a base (21, 41, 51, 61, 71, 81), a support base (23, 43, 53, 63, 73, 83), and a shape memory alloy actuator (25). The shape memory alloy actuator (25) is fixedly connected between the base (21, 41, 51, 61, 71, 81) and the support base (23, 43, 53, 63, 73, 83), and the shape memory alloy actuator (25) is configured to drive the support base (23, 43, 53, 63, 73, 83) to move relative to the base (21, 41, 51, 61, 71, 81). The motor (20) further includes an eccentricity-prevention magnetic assembly (27, 47, 57), the eccentricity-prevention magnetic assembly (27, 47, 57) includes a first eccentricity-prevention member (271, 471, 571, 771, 871) and a second eccentricity-prevention member (273, 473, 573, 773, 873), the first eccentricity-prevention member (271, 471, 571, 771, 871) is disposed on the base (21, 41, 51, 61, 71, 81), the second eccentricity-prevention member (273, 473, 573, 773, 873) is disposed on the support base (23, 43, 53, 63, 73, 83), and when the motor is in a powered-off state, a first central axis of the base (21, 41, 51, 61, 71, 81) coincides with a second central axis of the support base (23, 43, 53, 63, 73, 83) under the action of magnetostatic forces between the first eccentricity-prevention member (271, 471, 571, 771, 871) and the second eccentricity-prevention member (273, 473, 573, 773, 873), to resolve the problem of eccentricity of the motor (20, 40, 50, 60, 70, 80).
