Easy to use Piezoelectric Motors

“Plug and play” ultrasonic motors for your application

WAVELLING® piezoelectric motors from TEKCELEO are very easy to use. Their “Plug&Play” operation allows for very fast results and helps to rapidly prototype any type of device that can benefit from the advantages of piezoelectric technology. Simply plug in the motor and enter instructions such as motor speed and desired angle for immediate results. As a result, our rotary piezo motors are widely used as precise actuator for high-added value devices :

  • Surgical robots (MRI compatible and small actuator) ;
  • Positioning devices for medical or optronics uses (high precision, holding torque, low footprint) ;
  • Actuator for satelites antennas (no electromagnetic signature, vacuum compatible, very low footprint and self-locking) ;
  • Miniature non-magnetic actuator for implantable and embedded devices.

As an innovative company, TEKCELEO is committed to promoting research and development, both on its products themselves and as a company. One of our primary objectives is to provide support to the scientific community, with a particular focus on medical and surgical applications. The company seeks to develop applications that can be adapted to the needs of its customers. As a result, we support our customer in their development and help innovators to use the best of piezo motor technology. 

Our technology overview

Piezo Motors with built-in encoder

Our line of piezoelectric motors, based on 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 a few 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 3N.m depending on the type of motor. Our range of piezo motors is one of the best in class in terms of low speed/high torque ratio, with a unique expertise in very small rotary piezo actuator (20 mm diameter).

TEKCELEO offers the following actuators, all of which allow non-magnetic configurations for MRI environments:

  • Diameter 20 mm (0.787 in)
  • Diameter 30 mm (1.18 in)
  • Diameter 75mm (2.95 in)

All of our drives incorporate speed/position sensors and can incorporate torque sensors depending on the application.

Piezoelectric motor technology for medical robotics in any environment

A unique range of non-magnetic motors

Tekceleo WAVELLING technology is based on a time-proven, particularly robust ultrasonic motor design, which makes it possible to develop an equally powerful motor without any ferromagnetic materials. Our motor range is doubled with 3 types of non-magnetic motors, to cover a wide range of uses in MRI environment:

  • 20mm diameter non-magnetic motor, unique in the world in terms of size/power ratio for this type of use;
  • 30 mm diameter non-magnetic motor, a modular motor allowing all types of uses, especially in surgical robotics;
  • 75 mm diameter non-magnetic motor, whose power allows to consider applications in MRI environment requiring a high torque/speed ratio, in particular for contrast products administration or others…

Our range of non-magnetic motors, recognized worldwide, is a key point of Tekceleo know-how. We also work with our customers in the context of technological partnerships to adapt our motors to specific environments or use cases.

Some uses cases

Laser turret control actuator
Development of a piezoelectric motorization with a hollow axis, with very high acceleration and very low speeds allowing to control the movements of an optronic turret (application laser guidance for decoy missiles).
Cube SAT

Nos produits sont utilisables dans l’espace grâce à leur résistance à de très basses températures et leur faible consommation d'énergie qui leur permet de s’adapter à différents appareils.

Nous avons travaillé en étroite collaboration avec l’université del valle du Guatemala afin qu’elle réussisse à lancer un Cube SAT dans l’espace. Il a été lancé par l’agence d’exploration aérospatiale japonaise (JAXA).

Qu’est-ce qu’un Cube SAT ?

Un Cube SAT est un type de satellite miniaturisé pour la recherche spatiale qui est composé de plusieurs modules cubiques de 10 cm de chaque côté. Les Cube SAT ont une masse maximale de 1,33 kg par unité et utilisent souvent des composants commerciaux pour leur électronique et leur structure.

L’université d’El Valle de Guatemala a utilisé notre moteur WLG-30-R dans leur Cube SAT, nommé QUETZAL 1, car il fournit un couple de maintien sans alimentation qui permet à la caméra multi spectrale de verrouiller sa position sans consommer l’énergie des batteries. Notre moteur à ultrasons WLG-30-R pilote la caméra multi spectrale qui sert à recueillir les données pour la préservation des ressources naturelles.
