Automation Direct STP-MTR-23079 Stepper Motor

Automation Direct STP-MTR-23079 SureStep Stepper Motor is a NEMA 23 frame, single-shaft bipolar stepping motor designed for precise open-loop positioning in compact automation systems. It delivers 276 oz-in of holding torque, a 1.8-degree full-step angle (200 steps per revolution), and a 2.8 A per-phase current, compatible with a wide range of stepper drivers while providing strong low-speed performance. The motor uses a four-conductor bipolar winding, features a front shaft diameter of 1/4 inch, and carries an IP40 enclosure rating for basic protection in typical industrial environments; a 12-inch cable with four leads terminated by a connector simplifies installation and wiring. This model is part of AutomationDirect’s SureStep family, and related variants include STP-MTR-23079D (dual-shaft) and STP-MTR-23079E (encoder-equipped), offering options if a rear shaft or feedback is desired for more demanding applications. Note that this is the single-shaft version of the family, optimized for compact installations where encoder feedback is not required and where a straightforward, reliable stepper motor is desired.
