PiezoMotor LR17 - Presented During MD&M West

The LR17 expands MICROMO's strong line-up of piezo technology from PiezoMotor and is offered with an integrated absolute encoder. The compact LR 17 is a mere 17 mm in diameter and has all the benefits coming from the Piezo LEGS technology. The stall torque from the motor is 30 mNm, which is high compared to its small size. Because of the self-locking feature of the friction drive, the motor can hold position without consuming any power. The integrated 15 bit magnetic absolute encoder gives a closed loop resolution of 0.2 milli-radians (0.01º). Through the Piezo LEGS technology, you get an amazing sub-micro-radian resolution in open loop.

00:00:02 hi my name is Kevin Dixon today I'm here to mdn n West with Mike Romo and talking about the Piazza motor product we're introducing a new rotary motor to the Piazza legs family the lr 17 motor it's a small and very precise motor for high precision motion with this product you could easily position on a milliradian level using the integrated high resolution encoder but get selects

00:00:28 technology actually allows for even higher resolution moves down to sub micro Radian steps the motor is the smallest rotary Piazza motor we have released yet only 17 millimeters in diameter still you're getting quite a lot of torque out of this small sized motor with the pr2 legs direct drive you have up to 30 million Newton meters of torque without the need for gearbox the

00:00:51 direct drive also means this motor will have a serie backlash and that it's self locking it can hold its torque without consuming power which is great for moving whole applications and because of its size it will often fit where other motors will not the Piazza motors both are rotary and our linear versions are working on the same principle internal getso electric actuators that elongate

00:01:14 and bend to move the preloaded drive ring connected to the shaft this unique working principle allows for extremely small but distinct increments and by taking thousands of steps per second it's possible to get speeds up to 20 rpms the dynamic range is outstanding from 20 or pm's you can smoothly go down to moving at extremely low speeds and stop at any instance well in place it

00:01:38 will hold without consuming any power besides being very compact strong and precise the Piazza legs motors also benefit from their non magnetic properties in the family-owned motors where we actually have both completely non-magnetic options as well as versions for vacuum the pets legs is a clear favorite for high-precision systems as well as high-volume products with the

00:02:00 addition of the small and compact LR 17 we feel it's going to open up for completely new application areas and make possible for new developments with a medtech in other fields where precision and compact size is key so we ask anyone who's interested in our products to check out their webpage piazza motor calm or talk to the people at micro mode
