Ultrasonic motor

详情

Ultrasonic Motor: small size, a low speed, and high torque,  and is excellent in a response and silence.
Moreover, because it has high holding power at the time of un-applying an electric current, 
the moving part which does not use reduction gears can be built.

Because the Ultrasonic Motor uses neither the coil nor the magnet, it is not affected about operation 
of a motor by the influence of magnetic.
And an ultrasonic motor does not generate magnetism during rotation.For this reason, the stable operation 
in strong magnetic field environments, such as near MRI and superconductivity experiment equipment, is possible.

Now, Ultrasonic Motor is used for the following uses.
　　　・ Autofocus of a camera
　　　・ Control part of a measuring instrument
　　　・ Actuator of the lens mirror of optical equipment
　　　・ Control device of the antenna of an artificial satellite
　　　・ Gripper for the robots for industry
　　　・ Automatic controller of a rolling screen
　　　・ Conveying machine of parts
　　　・ Attitude control of the measuring instrument near MRI
　　　・ Actuator within High Magnetic Field Environment
