New Scale Technologies Inc. has introduced a benchtop motor controller that features an ActiveX command library and a USB connection. The SQ-2300 series simplifies computer control of the company’s piezoelectric Squiggle motors and closed-loop linear nanopositioning stages. Multiple controllers can be connected to one PC and driven simultaneously from a single screen for multiaxis set-and-hold positioning. The motor speed can vary continuously from microns to millimeters per second with better than 20-nm resolution. The controller’s input power is 12 or 24 V at 500 mA, with typical current of <200 MA and an output voltage of ∼200 V rms.
