Full featured microstepping drive is a real space saverAvailable from Mclennan, Applied Motion Products' STR2-nano microstepping motor drive delivers advanced features for open-loop motion control in a very compact package measuring just 34x35x16mm (length x width x height). With selectable current control from 0.3 to 2.2Amps/phase and with a 24V DC supply voltage, the STR2-nano is aimed at OEM machine and automated positioning applications where space is at a premium but performance cannot be compromised.

The STR2-nano has 16 selectable microstepping emulation/resolution settings from 200 to 20,000 steps/rev. Step-and-direction or CW/CCW pulse control are available and advanced digital current control technology features include automatic idle reduction for improved efficiency and lower heating, as well as electronic damping through smoothing and step filters for enhanced anti-resonance and quiet performance. A 30-pin header connector and multiple dip-switches enable easy set-up and installation with no need for software. Built-in safety includes under- and over-voltage protection.

This tiny drive has an operating temperature range of 0–40degC and may be heat-sink mounted or fan-force cooled for use with higher currents and more demanding start-stop performance. A wide selection of compatible permanent-magnet microstepping motors from NEMA size 11 to 23 are available with full support from Mclennan.

According to Mclennan, the STR2-nano is cost-effective for linear or rotary positioning in medical/laboratory equipment, small mechatronic and automated systems, power tools, battery-powered portable instruments and many other industrial and research-based motion control applications where space saving and/or high performance are required.
