Stepper motor-based leadscrew actuators are a cost-effective solution for simple positioning tasks with comparatively small forces. We offer such linear leadscrew actuators based on so-called tin-can motors as well as on hybrid stepper motors (DSM4234LN series). Both variants are offered with or without anti-rotation feature with a front mounted leadscrew (captive leacsrew) and also with a leadscrew passing through the motor (non-captive leadscrew).
The linear stepper motor leadscrew actuators of the PFCL series from Nippon Pulse (NPM) are based on the PF/PFC series tin-can stepper motors in sizes 25 and 35 and offer a linear stroke of up to 60mm as standard. The leadscrew pitch can be selected from 0.48mm, 0.96mm or 1.2mm. With step angles of 7.5 ° or 15 °, full steps of 0.01mm, 0.02mm, 0.025mm, 0.04mm or 0.05mm result accordingly. In the PFCL25 size, a captive linear leadscrew actuator with already integrated anti-rotation device with a stroke of up to 19mm is also available. Various uni- or bipolar windings for different voltages and different magnetic materials make the selection flexible for a wide range of applications. Other customer-specific requirements can also be met on request. The PFCL linear leadscrew actuator series offers a good cost/performance ratio with excellent quality and is well suited for use in mass applications in medical devices, as well as printers, fax machines, but also analytical equipment and industrial plants.
The hybrid stepper motors of the DSMH series in Nema standard can now be supplied by Geeplus as stepper motor linear actuators. For this purpose, the motor shaft is designed as a trapezoidal threaded spindle. In principle, all hybrid stepper motors of the DSMH series can be modified accordingly and there is flexibility in the choice of stroke length and leadscrew pitch. Optionally, an anti-rotation device is also possible.
