OUR TECHNOLOGY WAVELLING TM PRESENTATION The WAVELLING Technology developed and patented by relies on the piezoelectric actuation technology using mechanical waves. This operating mode provides a high power density combined with good efficiency for small motors (<20W mechanical). The motor has a very simple and purely mechanical structure (no winding) facilitating integration. Benefiting from its expertise, has developed a range of piezoelectric motors incorporating speed/position sensors and torque sensors giving these motors outstanding properties for light weight robotics applications, haptic interfaces, low-energy electro-valves, mini metered dose pumps and optronic equipment control applications (gimbal for drones ). Each type of motor can embed a speed-position sensor and/or a torque sensor. Output signals of the sensors can be directly used on the motor s control board (Cf. characteristics). ADVANTAGES Light and compact design (built-in sensors) Pancake shape ultrasonic motor Stepper motors competitors (or direct drive high torque motors) High torque / low speed. No-reducer (direct drive) No-power supply holding torque (built-in brake) No electromagnetic disturbances Silent, vibration-free Modular design : it can be fitted into the very core of the mechanism 0.01 precision (depends on the sensor) Fast mechanical response <1ms Operating temperatures : -20 + 140 C High shocks and vibrations resistance (compact) Torque or speed control (depends on the built-in sensors) Very easy to control thanks to its responsiveness and its built-in sensors.
