A very small, ultraflat stepper motor is now available from Nanotec Electronic US Inc. The STF2818 model has a flange size of 28 mm and is only 9.4 mm high. The STF2818 is the second ultraflat stepper motor in the product line, in addition to the ST6318. Originally, the small stepper motor was developed for feeder applications in the semiconductor industry, where components are supplied on rolls. With a rotor inertia of 1.7 gcm² and a holding torque of 0.98 Ncm, it reaches a considerable speed for its size. In combination with a step angle of 1.8°, the STF2818 is therefore also suitable for many other applications, including installation in a stirrer. The ultraflat stepper motor is optionally available with a flat-sided shaft.
