The new 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.
The LR17 is the first motor in a series with four different sizes. It allows MICROMO's customers to have a very compact motion solution, including sensor for easy integration.
