Piezo LEGS® Rotary 50mNm Non-magnetic Vacuum

LR50 version 12D — Non‑magnetic — Vacuum

Non-magnetic housing makes this motor suitable for use even in the most sensitive equipment. This motor can for example be used inside of an MRI scanner without creating image artifacts. Compact in size but surprisingly strong, this motor delivers up to 50 mNm torque.

  • Non-magnetic and suitable for sensitive equipment

    Quick response and fast settling time, the LR50 non-magnetic motor delivers high torque output without backlash or mechanical play. Motor is designed for use in environments that require a completely non-magnetic and/or a vacuum-compatible motor.  The direct friction drive of the Piezo LEGS® motor ensures power-off holding torque without power consumption, and the patented technology enables positioning down to 0.05 microradian (almost a millionth of a degree). The motor is ideal for ‘move-and hold’ applications that put a premium on precision, instant response and low power consumption.

    Piezo LEGS® motors don’t have the windings of a DC motor and will not be a source of magnetic flux. Motor housing and other parts are made from non-magnetic alloys. The LR50 is compatible to use even inside an MRI machine without disturbing the image. Non-magnetic motors have a magnetic flux density of less than 1 nT (sensor sensitivity in reference measurements) at a distance of 10 mm from the motor housing.
