Product Description:

The M061-LE-542 is a stepping motor produced by Danaher within the Slo-Syn Stepping Motors series. As a hybrid stepper, it converts pulse trains from an indexer or microstepping drive into incremental shaft rotation. This controlled movement supports the positioning of actuators, conveyors, and metering devices in industrial automation.

The motor follows the NEMA 23 mounting pattern, and its square frame measures 60 mm across, allowing it to fit standard size-23 installations without mechanical changes. It provides a minimum holding torque of 75 oz-in in bipolar two-phase-on drive mode and 60 oz-in with unipolar excitation, supplying sufficient stall torque for moderate indexing tasks. Step accuracy remains within ±3% of the commanded increment, supporting repeatable positioning when the motor is paired with an open-loop controller. Eight flying leads simplify wiring to series- or parallel-connected windings. This lead arrangement supports installations that use crimp or screw-terminal blocks instead of molded connectors. A single-stack magnetic circuit keeps the axial length short, while the rotor inertia of 0.0017 oz-in-s² reduces settling time during rapid start-and-stop cycles. Residual detent torque is limited to 1.0 oz-in, reducing cogging when phase current is removed.

Operation is permitted up to a case temperature of 100 °C, so forced-air cooling is usually unnecessary during typical duty cycles. The shaft can withstand a thrust load of 25 lb and an overhung lateral load of 15 lb, enabling direct coupling to light lead screws or timing pulleys without external support bearings. Its net mass is 1.3 lb, while its shipping weight is 1.5 lb. The low mass reduces the load added to gantries and end-of-arm assemblies. Its compact frame, short axial profile, and available torque support use in laboratory instruments, small pick-and-place axes, and compact packaging machinery where installation space is limited.
