Product Details

NEMA17 Stepper Motor LDO-42STH48-2004AC(VRN)

The NEMA17 stepper motor LDO-42STH48-2004AC(VRN) is a bipolar motion motor for compatible 3D printer motion systems, light-duty automation, positioning mechanisms, machine repairs, and custom electronics projects. With a 47 mm body length, 1.8° step angle, 2.0A rated current per phase, and 59 Ncm holding torque, this motor is suited for applications that require stronger controlled rotational movement in a standard NEMA17 frame size.

NEMA17 Stepper Motor for Motion Systems

This NEMA17 stepper motor is designed for applications that require repeatable rotational movement and stable holding torque. It can be used in compatible printer motion systems, linear motion assemblies, belt-driven axes, positioning fixtures, light-duty automation projects, and equipment repairs where the electrical and mechanical specifications match the design.

47mm Body with 5mm D-Cut Shaft

The motor features a 42 × 42 mm frame size, 47 mm body length, 5 mm shaft diameter, 24 mm shaft length, and 15 mm D-cut length. The 5 mm D-cut shaft helps provide a secure interface with compatible pulleys, gears, couplers, or drive components.

2.0A Motor with 59 Ncm Holding Torque

This NEMA17 stepper motor is rated at 2.0A per phase and provides a listed holding torque of 59 Ncm. The higher torque rating makes it useful for compatible motion systems where the motor must hold position and move loads consistently. Confirm driver current settings, cooling, firmware configuration, and mechanical load requirements before installation.

Connection and Cable Note

The current product page lists the connection colours as A+ black, A- green, B+ red, and B- blue. It also states that the cable is sold separately. Confirm pinout, coil pairs, connector style, and cable compatibility before connecting this motor to a stepper driver or control board.

Compatible Build Note

The live product page lists this motor for Voron 2.4 applications and notes that four pieces are required for that specific use. For other machines or custom projects, verify body length, shaft size, torque, current rating, wiring, and mounting compatibility before ordering.
