Linear Motors
•LinMot linear motors employ a direct electromagnetic principle. Electromagnetic force provides direct linear movement without the use of cams, gears, belts, or other mechanical devices. The motor consists of only two parts: the slider and the stator. The slider is a precision assembly that consists of a stainless steel tube, which is filled with neodymium magnets, that has threaded attachment holes on each end. The stator, consisting of coils, the bearing for the slider, position sensors and a microprocessor board, is designed for use in harsh industrial environments.
•The standard motors are available in 15 different motor configurations with peak forces of from 33 to 580 N (7-130 lbs). A total of over 300 standard motor specifications with strokes lengths of up to 1500 mm (5 feet) are available. In addition, the module design of LinMot® motors allows custom designs even in moderate quantities.
