42mm Stepper Motor 1.5A Precise

This 42mm (NEMA 17-size) bipolar stepper motor features a rated current of 1.5 A, rated voltage of 3.0 V, phase resistance of 2.0 Ω, and phase inductance of 3.4 mH (note: 'MΩ' in source is physically inconsistent — corrected to standard unit mH based on typical 42mm motor specs; original text likely misstated 'mH' as 'MΩ'). It delivers a holding torque of 290 mN·m and positioning torque of 12 mN·m. Constructed with a robust metal body for thermal stability and mechanical durability. Designed for 2-phase operation, it supports precise open-loop motion control in compact printer accessory applications. The motor enables smooth, low-vibration stepping ideal for paper feed mechanisms, carriage movement, or auto-cutter modules in desktop and industrial printers. Its consistent torque output across low-to-mid speed ranges ensures reliable layer alignment and repeatable positioning without stalling under typical printer load conditions. Intended for integration into existing printer accessory systems — compatible with common driver boards (e.g., A4988, DRV8825) when configured for 1.5 A current limit. Mounting conforms to standard 42mm frame dimensions with through-hole screw pattern. Not a plug-and-play OEM replacement; requires matching driver configuration and mechanical adaptation.
