LDO 42STH48-2504AH(S35) Stepper Motor
The LDO 42STH48-2504AH(S35) is a premium NEMA 17 stepper motor designed for high-performance 3D printing and automation systems. With a compact 48mm body and 2.5A rated current, it delivers reliable torque and smooth motion—ideal for CoreXY setups, Z-axis drives, and multi-motor configurations like Voron AWD.
Technical Specifications
- Step Angle: 1.8° (±5% @ full step, no load)
- Rated Current: 2.5 A
- Resistance/Phase: ~1.1 Ω
- Inductance/Phase: ~2.8 mH
- Holding Torque: 5.5 kg·cm
- Shaft Diameter & Length: 5 mm (D-shaft), 35mm long
- Body Length: 48 mm
- Wiring: 1m PTFE cable with 4-pin JST-XH
- Weight: ~350 g
- Temp Rating: Steppers are specified for a higher-temperature for enclosed builds. We still recommend for environment temperatures above 40C to reduce the motor current to increase life expectancy of the stepper.
Key Features
- High Torque Output: Ideal for belt-driven systems and AWD upgrades.
- Thermal Resilience: Rated for high-temperature environments, including enclosed chambers.
- Plug-and-Play Wiring: Pre-terminated PTFE cable with JST-XH connector for clean routing.
- Precision Machining: Low axial and radial play for smooth motion and reduced vibration.
- Voron-Ready: Fully compatible with 2.4 & Trident Voron kits and Voron AWD upgrade kits.
Applications
- Voron 2.4 & Trident (XY and Z axes)
- Recommended by LDO for the 2.4/Trident AWD kit
- CoreXY motion systems
- CNC gantries and linear actuators
- Robotics and automation platforms
