About this item
The NEMA 17 bipolar stepper motor is a two-phase hybrid stepping motor with a 42.3 mm square frame and 48 mm body length that produces precise rotational motion in discrete 1.8 degree increments without a position encoder. This 48 mm class (represented by the OMC-StepperOnline 17HS19-2004S1) delivers a holding torque of 59 Ncm at 2.0 A per phase, with a phase resistance of 1.4 ohm and phase inductance of 3.0 mH, making it well suited for medium-load positioning applications. It is driven exclusively by a stepper motor driver (such as A4988, DRV8825, or TMC2209) via step and direction logic or PWM current chopping, and it operates in full-step, half-step, or microstepping modes depending on the driver. The motor has no onboard feedback or encoder, so position integrity relies on open-loop step counting unless an external encoder is added for closed-loop operation. Typical applications include 3D printer axes, CNC router tables, pick-and-place machines, and camera sliders requiring repeatable low-speed precision motion.
Dianao NEMA 17 Stepper Motor, 48 mm Body Length is listed in the Servos, Actuators & Gripsters range from Dianao for trade buyers comparing Automation & Robotics. Use product SKU DN-NEMA17-48 when checking the exact line, option or replacement requirement. The page combines the current price, supplier-backed availability and recorded product data in one place so the listing can be assessed before it is added to a project order.
Recorded details for DN-NEMA17-48 include Holding torque: 0.55 N·m; Step angle: 1.8°; Rated current: 1.5 A/phase; Shaft: 5 mm D-cut. Check every applicable dimension, rating, material, included part and compatibility statement against the equipment or workpiece already on site. Supplier terminology can describe a family rather than every variant, so the SKU and specification table should control the final selection.
