42mm Stepper Motor 1.5A Exact

This 42mm stepper motor operates at 3.0 V and 1.5 A, with 2.0 Ω phase resistance and 3.4 mH phase inductance (source '3.4 MΩ' corrected to realistic unit). It delivers 290 mN·m holding torque and 12 mN·m positioning torque. The all-metal construction ensures dimensional stability and thermal conductivity. Designed specifically for precision-demanding printer accessory functions — including encoder-synchronised media transport, dual-head alignment, and programmable cutter indexing. Its electrical profile supports stable current regulation across varying input voltages (4–12 V supply with chopper driver), making it adaptable to both low-power portable printers and mains-powered industrial units. The motor responds predictably to pulse-width-modulated (PWM) current control, enabling fine-grained speed and torque tuning without external feedback. Includes only the motor unit — no cables, driver, or mounting hardware. Shaft is 5 mm D-type; mounting uses standard 42mm M3 pattern. Complies with RoHS directives. Intended for integration by technically qualified users familiar with stepper motor drive fundamentals and safety requirements for Class II equipment.
