Low Currents – Higher Voltages
Nanopositioner design for ultra-low temperature environments
Ren-Sci motors are engineered to have significantly lower capacitance compared to conventional cryogenic motor solutions. While competitor motors operate at lower voltages (30-70V) and higher currents (tens of amps), Ren-Sci took a different approach. Their motors run at higher voltages (50-600V) and require only hundreds of milliamps
ABOUT
SYSTEM FEATURES
Ultra low heat dissipation!
Compare a typical leading vendor scenario, 60 V, 1 kHz, 5 uF, so the power pumped into that capacitor is CV^2/2 times frequency which is ~ 9W. The analogous situation for our motors is 200 V, 1 kHz, 5 nF, which is 0.1 W, so using 90x less energy to get the same motion (and thus 90x less heat dissipation)
Spectacular specs
Multidirectional Repeatability: 8 to 150nm
Sensor resolution 2 to 20nm
Closed loop mode minimum incremental motion : 10 nm
Market standard = 5 μm, 200nm, 400 nm
Ren-Sci improves 2 orders of magnitude
Repairability for an outstanding service life
As such, Ren-Sci have intentionally designed his motors to have user exchangeable actuators and we supply 2 extra actuators per axis. So, each axis should easily last 7-10 years, even under heavy use. But even if you go through those sooner, just call us and we’ll overnight you another actuator. Your days of waiting 6 weeks for a repair are over!
UHV and non-magnetic by default
All Ren-Sci motors are UHV compatible, bakeable to 120 C, and made with non-magnetic materials
Purpose built for cryo
Several suppliers for ambient piezo based motors will simply try to plop it in a cryostat and hope for the best. Our motors were carefully engineered with extreme attention to thermal contraction, capacitance losses in cryo, minimal friction at the bearing interfaces, and low current operation
Excellence in craftsmanship
No lubricants are used, solid-state or otherwise. Instead, we use diamond polished surfaces and extremely high precision on our machined parts (sub 2um parallelism on every part), so that there is no need for the use of lubricants

We rarely have the opportunity to distribute products that bring real new value to researchers and easily solve one of their persistent challenges.
Research applications have evolved towards ever-smaller objects, in ever-lower-temperature environments, while positioning tools have lagged behind.
Ryan has applied all his expertise to bridging this gap, and we are delighted that he has chosen us to spread the word locally.
Discovering and promoting manufacturers like Renaissance Scientific is at the core of what we want to do with Qnity.
