UPPSALA, Sweden, July 28, 2013 — PiezoMotor AB has released LR17, a 17-mm-diameter piezo LEGS rotary motor with an integrated absolute encoder for compact motion applications.
The device features 30-mNm stall torque from the motor and a self-locking friction drive to hold the motor in position without consuming power. The integrated 15-bit magnetic absolute encoder provides closed-loop resolution of 0.2 mrad. The Piezo LEGS technology enables submicroradian resolution in open loop.
The LR17 model is the first motor in a series of four different sizes, the company said.
