Leadshine 3S Three-Phase Stepper Motors
Leadshine 3S Three-Phase Stepper Motors
Leadshine 3S motors use a three-phase hybrid stepping design for incremental rotary positioning. The family includes NEMA 23, 34 and 42 frames; the appropriate torque and winding depend on the selected model. A Cloudray listing for a 573S15-L motor with a fixed pulley provides an indicative USD 40 example, rather than a price for every 3S configuration.
Review Summary
A useful option for an open-loop positioning axis when its operating torque remains comfortably inside the motor-and-drive speed curve. Three-phase commutation and the 1.2-degree mechanical step angle require a matching driver; a standard two-phase driver is not interchangeable.
