Ultrasonic Motor Drivers

Analog/digital control model

Ultrasonic motors (piezosonic motors) are quiet, high-torque motors that use piezoelectric ceramics, which expand and contract when voltage is applied, as their drive source. Unlike typical motors that use electromagnetic force, they do not use coils or magnets, but operate using frictional force, making them small and lightweight, yet capable of use in magnetic fields and without backlash. Taking advantage of these characteristics, they are ideal as direct drive motors for positioning stages, belt conveyors, angle indexers, robot arms, and other posture control devices, as well as motors for MRI and semiconductor manufacturing equipment.

Control circuit that controls the rotation direction and speed of the ultrasonic motor

We have developed a driver that can be used with the same feeling as controlling a DC motor. You can easily control the ultrasonic motor from a board equipped with analog voltage output functions such as a PLC (sequencer), Arduino, or MBE. We also have a model that does not use analog voltage for control and allows full digital control via USB connection.
