LDO-36STH20-1004AH 36mm Pancake Stepper Motor – High Temp 1.0A Ø5mm D-Cut Shaft

The LDO-36STH20-1004AH is a compact 1.8° 36mm round pancake stepper motor designed for space-limited 3D printer motion and extrusion applications. Featuring a short 20mm max body length, 95mN·m minimum holding torque, and Class H 180°C insulation, it is well suited for enclosed printers, compact toolheads, and lightweight direct-drive setups.

This version comes with a Ø5mm full D-cut shaft and an 800mm high-temperature Teflon wire harness with an XH2.54-4P connector. No integrated drive gear is included, so please verify gear compatibility with your extruder design before installation.

Key Features

Compact 36mm Pancake Design

The 36mm round frame and 20mm max body length help reduce toolhead mass while keeping sufficient torque for compact extruder and motion applications.

High-Temperature Construction

Built as an HT stepper motor with Class H 180°C insulation and 200°C-rated Teflon wire, this motor is well suited for enclosed 3D printers and elevated chamber environments. LDO’s high-temperature motor series is commonly positioned for 3D printer extruder application.

1.0A Phase Current with 95mN·m Holding Torque

Rated at 1.0A DC per phase, this motor provides 95mN·m minimum holding torque, balancing compact size with usable torque for lightweight direct-drive systems.

Ø5mm Full D-Cut Shaft

Equipped with a Ø5mm full D-cut shaft, this motor provides mechanical engagement with compatible gears, pulleys, or drive components than a plain round shaft.

Recommended for:

Compact 3D printer toolheads requiring a 36mm round pancake stepper

Lightweight direct-drive extruder setups using a Ø5mm D-cut shaft

Enclosed 3D printers where higher motor temperature resistance is preferred

Custom Voron-style, DIY CoreXY, or compact motion projects where the mount matches the drawing dimensions

Please note: many merchant listings for similar LDO 36STH20 motors reference AHG geared variants for Voron Stealthburner, Clockwork 2, Sherpa, Galileo, or Orbiter-style extruders. Those versions may include integrated 9T / 10T gears or different electrical values. This product page is written for the uploaded LDO-36STH20-1004AH drawing and product photos, which show a Ø5mm full D-cut shaft without an integrated gear.

Installation Notes

Verify extruder compatibility - Confirm that your extruder or mount supports a 36mm round NEMA 14-style pancake motor.

Set motor current correctly - Configure the current according to your controller and cooling setup. This motor is rated at 1.0A per phase.

Check shaft and gear compatibility - Before installation, ensure your gear or pulley is compatible with the Ø5mm D-cut shaft (no integrated gear is included).

Verify coil pairs - Confirm coil wiring before powering the motor to avoid incorrect rotation or vibration.

Route wiring safely - Keep the wire harness away from hotend heater blocks, moving belts, and sharp printed edges.
