Main Advantages
Our miniature motors offer precise and smooth motion, making them ideal for applications like surgical robots and injectors, where accuracy is critical. They have a high torque-low speed ratio, allowing for efficient and accurate movement even in tight spaces.
Additionally, our range of piezo motors offer the possibility to control them in Direct Drive, which eliminate the need for gears and other mechanical components. This not only simplifies your design but results in a more reliable conception.
Another advantage of ultrasonic motors is their high precision and almost no latency. They can provide very precise positioning and movement, making them ideal for use in applications that require high levels of accuracy, such as in surgical robotics, pharma processes or aerospace optronics.
At Tekceleo, we specialize in the design and manufacture of ultrasonic motors and have been at the forefront of innovation in this field for many years. Contact us if you want to know more !

Non-Magnetic Motors
Our Wavelling Technology Overview
Travelling Wave Non-Magnetic Piezo Motors with Built-in Encoder
At Tekceleo, our Wavelling technology offers exceptional precision and control with our Travelling Wave Piezo Motors. This unique technology utilizes ultrasonic waves to create mechanical vibrations that are then converted into rotary motion. The result is smooth and precise motion control that is ideal for applications such as robotics, medical devices, and automation equipment.
Our unique WAVELLING® know-how, ranges from 20mm (for miniature motors) to 75mm diameters. The diversity of our line of motors enables them to achieve a wide range of performances and uses, ranging from nominal speeds of below 1 RPM to 600 RPM depending on the type of motors, all without a reducer (no backlash or jerks). The nominal torques can vary from a few mN.m to 2N.m depending on the type of motor.
Our Travelling Wave Piezo Motors also come with built-in encoders, providing accurate feedback on position and velocity. This feature ensures that your equipment operates precisely and reliably, with the added benefit of reduced wiring and installation time. Additionally, our motors have a high torque-to-weight ratio, making them ideal for applications where space is limited or weight is a concern.
