Vertical lifting platform

Ultrasonic piezo motor | XUMU

World's fastest ultrasonic motor. Direct-drive, non-magnetic and equipped with integrated encoder.

The XUMU is a direct-drive ultrasonic piezo motor, with integrated controller, allowing for an extremely compact design and easy integration in applications like micro automation, sample positioning and OEM motion projects.

The XUMU comes with a ceramic strip which can be attached to the object you wish to move. A detailed explanation can be found below.

Ultrasonic motors by Xeryon

The non-magnetic XUMU motor is driven by the Crossfixx™️ ultrasonic piezo technology, allowing for a silent and fast positioning of any object. With a direct-drive force of 3N this is the world’s leading piezo motor in terms of force, speed and integrability.

The lifetime of over 1000km (or 10 million cycles) puts the XUMU at the top, supporting a wide range of applications. The XUMU motor is a real OEM product but a break-out board is available for test setups.

How it works:

1. The motor's ceramic tip vibrates in an elliptical pattern at a very high frequency.

2. When the tip contacts another object, this vibration will result in movement of said object.

3. The XUMU comes with a ceramic strip, which can be attached to the object you wish to move. Both linear and rotary movement is possible.

4. The motor can be controlled by analog control or PWM. A version with an external controller is also available.

The XUMU comes with the ultrasonic motor with suspension, an adhesive ceramic strip, mounting screws and an optional break-out board for test setups (see picture below).

Controlling the XUMU

You can control the speed of the XUMU ultrasonic motor with an analog signal on the “SPD” pin. The analog input voltage can range from 0V to 3.3V which corresponds to lowest speed (standstill) to full speed.

You can control the speed with a PWM signal on the “SPD” pin. This signal should not exceed 3.3V and the frequency has to stay between 200 Hz and 200 kHz. By varying the duty cycle of the PWM signal you can control the speed from the lowest speed (standstill) to full speed.
