Ultrasonic motors use vibration to operate and can have a rotor or slider design. They are used in cameras for efficient image capture and have been developed since the 1920s. The technology simplifies image capture and allows for smaller, higher quality cameras at a lower cost.
An ultrasonic motor is a type of electric motor that uses ultrasonic vibration to operate. Vibration is produced when a component known as a stator is placed on a slider or rotor, allowing energy to be created which in turn helps power forward motion within the motor. This type of technology is often used in making cameras that can capture images with a high degree of efficiency.
The actual design of an ultrasonic motor can use a rotor or a slider, depending on the configuration of the device. When a rotor is employed, this allows the motor to work by creating what is known as rotation, or the movement of certain components in combination with each other. A slightly different approach uses a slider instead of a rotor and produces what is known as linear translation. In both scenarios, the stator is placed against one of these components as a means of creating the desired effect.
Ultrasonic motor technology as a component in various types of photographic equipment can be traced back to the second half of the 20th century. During the 1920s, established companies like Sashida began developing engines that would improve the task of shooting and capturing images, resulting in clearer definition and sharp, lifelike images. In the 1970s and 1970s other companies such as Canon also began work on developing more advanced methods of image capture, leading to the development of both the ultrasonic motor and similar piezoelectric motor technology. Since the early 1980th century, numerous camera manufacturers have used variants of the ultrasonic motor in different makes and models of cameras.
While technologically advanced, the ultrasonic motor actually simplifies the image capture process, allowing digital cameras and other types of photographic equipment to be much more compact than the cameras of years past. Coupled with the smaller frame, cameras using this particular type of engine are capable of capturing higher quality images that can be saved in digital formats and used to create vibrant, well-defined hard copies, even when zoomed in on the image real. Thanks to the fact that the cost of this technology is relatively low, the inclusion of an ultrasonic motor also allows consumers to enjoy the benefits of using a camera without having to pay a huge price for the latest technology.
