|
|
| stepper motor An electric motor whose rotor does not rotate continuously, but steps from being aligned with one set of stator windings, to being aligned with the next set. In this way, precise steps of fractions of a rotation can be achieved under electronic control |
|
|
|
|
| stepper motor controller |
|
|
|
|
| stepper motor driver Electronic apparatus for supplying controlled electrical pulses to an electric stepper motor (each pulse stepping the motor forward or backward by a precise faction of a revolution) |
|
|
|
|
| stereomicroscope A microscope, with two sets of optics, side-by-side. Originally to give stereo vision to the observer, with one set of optics for each eye, it can also be used for collecting stereo information for storage or processing |

| submersible pump A pump (usually for water, and driven by an electric motor) that can be lowered into the fluid itself, and that then pumps the fluid up a vertical pipe |
|
|
|
|
| suction cup A type of gripper that works by making an air-tight seal between the rim of the flexible cup and the surface of the object, and then maintaining a pressure within the cup that is lower than that of the atmosphere |
|
|
|
|
| surface grinding machine A machine with an abrasive belt or disk for shaping the surface of an object |
|
|
|
|
| surge arrester An electrical device for preventing lightning and other types of voltage surge from passing (from the external lines though to the interior equipment, for example) |
