Therefore, we reduce development cycles while guaranteeing product quality and manufacturing scalability.īeing dynamic is our highest priority, for our products and our mindset. These modules are adapted and combined to solve your specific actuation task. hpower actuators are based on different modules of actuators and contollers. We will not just find the right actuator for you, we will make sure that our system works in your environment. Together with you, we develop motion solution to solve current and future technical and business challenges. With hpower actuators, our team is going the next step: You are the expert of your application and we know the performance of our technology. hpower actuators inherit decades of expertise in the field of piezo technology, as well as customer feedback from various industries and application based experience. Together we are experts in dynamic motion technology. The accuracy achieved is in the order of 10 nm over a bandwidth of 500 Hz.Hpower actuators are developed by piezosystem jena, in cooperation with Piezomechanik GmbH. Real-time open and closed loop hysteresis compensation schemes were implemented leading to high accuracy positioning using piezoceramics. The real-time compensation technology leads to high accuracy actuators operating over a wide dynamic range. Examples given in this tutorial indicate a selection of the many applications common today. MMDL researchers have also developed technology to overcome hyseresis and drift in piezoceramics actuators. Piezoelectric actuators offer a solution to positioning tasks that require the highest accuracy, speed and resolution. The focus of this project is a finding a better signal control algorithm or a better mechanical system that can reduce inaccuracy effects while not compromising the motor’s advantages. The most advanced inchworm motor, developed by University of Toronto, shows improved performance (8mm/s and 20nm accuracy in nano regime). Therefore if there is no slippage (sufficient friction) upon contact between the clamp and slide, the result is desired movement of the slide. PD ceramic has over 30years of experience in piezo actuator research, development, and manufacturing. The motor clamp moves in the same direction as the slide. Our piezoelectric actuator research institute is within the top 3 in China as well. Therefore the force applied has to be large enough to avoid slippage upon contact. This force is perpendicular to the axis of motion. The movement of the slide is due to the force exerted by the motor clamp. The inchworm motor uses two clamps and an extension actuator to mimic inchworm movement. Optimal motor design is demanded in many fields of industries such as metrology, biomedical research, MEMS and semi-conductor fabrication. Basic working principles of these motors as well as actual prototypes are shown. Varieties of designs are available such as discontinuous motors (inchworm, caterpillar and walking) and ultrasonic motors (traveling wave, elliptical push, pi-shaped, and nanomotor).The MMDL motors are based on the inchworm principle and typically integrate three piezoceramic actuators inside a mechanical frame. The piezoelectric motor is the most commonly used smart material motor in the industry. Optimal motor design is demanded in many fields of industries such as metrology, biomedical research, MEMS and semi-conductor fabrication.Ĭurrently there is no piezoelectric motor that is capable of having accuracy within 20nm, adequate speed and stiffness. Currently there is no piezoelectric motor that is capable of having accuracy within 20nm, adequate speed and stiffness. MMDL researchers have developed high precision piezomotors that operate in the millimeter regime, micrometer regime and nanometer regime.
