High Torque Stepper Motor - 42K

The 42K Series High Torque Stepper Motors use advanced magnetic technologies to provide significantly higher torque levels than what is available in standard round motors. These motors are available in a variety of windings to meet any application-specific requirement. The 42K Series is the highest rated torque offered in the 42 Frame size, and is the closest match to the PacSci K42 series. The torque levels reached with this stepper motor line make them cost-effective alternatives to servo motors in many applications. These motors can be specified in place of standard motors to reduce system size and cost or increase system performace, without the need to go to larger sized motors or drivers.
See Accessories on this website for optional motor adders such as encoders, brakes, cables and connectors. For Gearbox options, see Gearboxes. For compatible drivers, see MBC10641, MBC082561 and MLA10641 Series, or Driver Packs.
