LDO-36STH20-1004AHG(XH)(DFH)

LDO high-temperature NEMA 14 pancake stepper for compact direct-drive extruders. The LDO-36STH20-1004AHG(XH) is a 1.8° LDO Motors stepper built for tight toolhead packaging, with a 20 mm body, 1.0 A/phase rating, and integrated 10-tooth gear.

Why this motor

• High-temperature construction: LDO specifies Class H insulation, with windings, bearings, magnetic steel, and plastic skeleton selected for up to 180°C insulation class.
• Compact extruder format: NEMA 14 pancake frame with a 20 mm body keeps weight and stack height down on direct-drive toolheads.
• Integrated drive gear: LDO lists a module 0.5, 10-tooth gear with 20° pressure angle; KB-3D lists the 2.5 mm shaft / integrated 10T format for this motor.
• Known Voron-style fit: commonly used for compact extruders such as Clockwork 2 / Stealthburner, Galileo, Orbiter-style, LGX Lite, and Sherpa Mini when your BOM calls for this motor family.

Compatibility notes

• Check your extruder BOM, gear requirement, connector, and pinout before installation.
• This is a stepper motor, not a complete extruder, not a drive-gear kit, and not a stepper driver.
• Pair with a compatible controller/driver such as the live BTT TMC2209 v1.2 Stepper Driver or BTT EZ2209 Stepper Motor Driver where your board supports it.
