NEMA17 42-23 Stepper Motor 1.0A 0.1Nm 42*23mm

The NEMA17 42-23 Stepper Motor (Model B01619) is a high-precision, ultra-compact 2-phase hybrid stepper motor designed for space-constrained motion control applications. With a slim body height of just 23mm, this motor is exceptionally well-suited for lightweight 3D printer extruders (such as pancake extruders), mini CNC machines, and laser engravers. It features a standard 1.8-degree step angle (200 steps per revolution), providing smooth, reliable, and highly accurate positioning.

Operating at a rated current of 1.0A and a rated voltage of 4.0V DC, this stepper motor delivers a holding torque of 0.1 N.m, making it highly efficient with low heat generation. The motor comes equipped with a 5mm D-shaped shaft for secure pulley or coupling attachment, preventing slippage during high-speed operations. It includes a 0.8-meter detachable cable with a PH-6P connector on the motor side and a standard XH2.54 connector on the driver side, ensuring plug-and-play compatibility with popular stepper drivers like the A4988, DRV8825, and TMC2209 on Arduino or RAMPS shields.

Features:

• Ultra-Slim Profile: Compact 23mm body height makes it perfect for lightweight extruder assemblies and compact DIY builds.
• High Precision: Standard 1.8° step angle ensures accurate microstepping and precise positioning.
• Secure D-Shaft: 5mm diameter D-shaped shaft prevents gear or pulley slippage under load.
• Detachable Cable: Includes a high-quality 0.8m PH-6P to XH2.54 connection cable for easy wiring.
• Low Heat & High Efficiency: Optimized phase resistance (4.3 ohms) and inductance (2.5mH) for cool and stable operation.
• Wide Compatibility: Seamlessly interfaces with TMC2208, TMC2209, A4988, and DRV8825 stepper motor drivers.
