Stepper Motors with Spur Gearboxes - 34YSG

The 34YSG Series Gear Motors offer a great value without sacrificing quality. A broad line of motor windings, gear ratios, and stack lengths are available off-the-shelf, or the motors can be customized to fit your machine requirements. The standard 8-lead motors can be connected in all possible configurations: series, unipolar, or parallel, to allow the maximum flexibility for your application. We can also customize the winding to perfectly match your voltage, current, maximum operating speed, and gear ratios.
See Accessories on this website for motor adders, such as encoders, cables and connectors. For compatible drivers, consider popular models MBC25081TB, MBC05641, MBC12101, MBC10641, MBC082561, and MLA10641.

To build a complete part number, select a motor from Table 1, and a gear ratio from Table 2.
