Stepper motor
Lin Engineering developed the SilverPak 17, a two-phase, 1.8° bipolar stepper motor with an integrated microstepping driver that delivers high performance. It features selectable step resolution from full-, half -, and quarter-step to eighth-microsteps; optically isolated step, direction, and disable inputs; and automatic current reduction with a disable switch. It operates on 12 to 24 V dc with low power dissipation and is offered in body lengths of 2.69, 2.92, and 3.24 in (68, 74, and 82 mm). Standard front-shaft extension length is 0.94 in (24 mm), and standard shaft diameter is 0.1968 in (4.3 mm). Other features include quiet operation, efficient current control, and 0.44 lb•ft (0.60 N•m) holding torque. Custom lengths and diameters are available.
