Linear dc servomotor weighs just 17g but delivers nearly 3N force(09/02/2011)
Faulhaber has added a smaller, high performance linear dc servomotor to its range. Based on its innovative QUICKSHAFT technology, the LM 0830 measures just 8x12x30 mm and weighs only 17 grams, yet it delivers a peak force of 2.74N and a maximum speed of 2.4m/s. The 4mm diameter forcer rod is available in different lengths to provide strokes of up to 40mm. The device incorporates three analogue Hall sensors for position and speed control feedback, generally avoiding the need for an encoder.
