LDO-35STH52-1504AH(VRN) High Temp NEMA 14 Stepper Motor for Voron V0.1/V0.2

The LDO-35STH52-1504AH(VRN) is a high-temperature NEMA 14 stepper motor designed for compact, high-performance 3D printer motion systems. Featuring a 52mm body, 1.5A rated current, and 0.37N·m holding torque, it is well suited for Voron V0.1 / V0.2 A/B motion applications where pace is tight but reliable torque is essential.

This version uses Class H 180°C insulation and UL1332 24AWG 200°C Teflon wire, making it a excellent choice for enclosed 3D printers and high-ambient-temperature environments. The motor comes with a 5mm D-shaft and XH-4 male connector, simplifying installation and replacement.

Key Features

High-Temperature NEMA 14 Motor

Built as a high-temperature version with Class H 180°C insulation, this motor is designed for enclosed printer environments where standard wiring and insulation may not be sufficient.

52mm Body with Strong Holding Torque

The 52mm motor length provides more torque than shorter NEMA 14 motors, delivering 0.37N·m holding torque for stable A/B axis motion in compact CoreXY printers.

5mm D-Shaft for Pulley Installation

Equipped with a 5mm D-shaped output shaft, this motor is compatible for common GT2 pulley setups used in Voron-style motion systems.

Pre-Wired with High-Temp Teflon Cable

Comes with UL1332 24AWG 200°C Teflon wire and an XH-4 male connector, reducing wiring effort and improving reliability in high-temperature printer builds.

This motor is suitable for the following applications:

• Voron V0.1 / V0.2 - Direct replacement for A/B axis motors
• Compact CoreXY 3D printers - Ideal for motion systems with limited space
• High-temperature enclosed printer builds- Withstands elevated ambient temperatures
• Any applications requiring a NEMA 14 motor with 52mm body length
• GT2 pulley-based motion setups - Works with standard 5mm D-shaft pulleys

Before purchasing, confirm your printer requires a NEMA 14 35mm frame motor, 52mm body length, 1.5A phase current, 5mm D-shaft, and XH-4 connector wiring.

Installation Notes

Set motor current according to your controller and driver configuration. The rated current is 1.5A per phase.

Confirm coil pairs before connecting to the driver, especially if your control board uses a different pin assignment. 

Use a pulley designed for a 5mm D-shaft.

Do not overtighten pulley set screws against the shaft.

Check motor clearance carefully - this motor has a 52mm body length, which may be longer than standard NEMA 14 motors.
