TEKCELEO-patented WAVELLING™

piezomotors technology uses piezoelectric or ultrasonic progressive wave principle. This technology offers a high power-to-weight ratio combined with high efficiency for ultrasonic motors or piezoelectric motor. TEKCELEO has developed a range of ultrasonic motors or piezoelectric motors with embedded speed/position sensors and torque sensors, resulting in outstanding properties for lightweight robotics, haptic interfaces, piezoelectric miniature pumps, piezoelectric miniature valves and for piezoelectric actuators dedicated to optronics or optomechanical applications. The range has been extended to the piezoelectric linear motors and the non-magnetic piezoelectric motors

ULTRASONIC MOTORS CHARACTERISTICS

• Ultrasonic motors compete with stepper motors
• Lightweight, compact design, pancake piezomotors
• High torque-low speed without reducer (direct drive-no backlash)
• No-power supplied high holding torque (no brake and no clutch)
• No electromagnetic disturbances (non-magnetic ultrasonic motors)
• Totally silent and vibration free piezoelectric motors (out of audio band)
• Modular design: it can be fitted into the very core of your mechanism
• Built-in precision capability: < 0.01° (depends on the embedded sensors)
• High controllability (mechanical time response #1ms, stepless, no backlash)
• Operating temperature (-20 +120°C) (option -40 +150°C)

PRODUCTS: A RANGE OF ULTRASONIC MOTORS

Our range of piezoelectric motors is based on 5 types of dimensions and mechanical output powers from diameter 20 mm to 75 mm and respectively 0.7W to 12W. These piezoelectric motors feature original properties given by embedded speed/position/torque sensors. The integration of the sensors into the structure of the motors is innovative and patented. Currently, WLG-20, WLG-30 et WLG-75 piezomotors are on presale:
