: While some generic 42-34 motors are rated at 1.5A, the BJ42D15 series used by Creality is specifically tuned for lower current (~0.84A) to maintain thermal stability. Holding Torque : Approximately 2.86 kg·cm (0.28 N·m). Dimensions : 42 x 42 x 34 mm (Standard NEMA 17 "42-34" frame). Shaft Diameter Input Voltage : Maximum 24V DC. Operational Features Stepper Motor Basics
26V DC (often driven by 24V power supplies common in industrial printers). Winding Resistance: 10 Ohms per phase. Rated Current: Roughly 0.8A to 1.0A per phase. Configuration: 2-Phase bipolar (4-wire). Typical Performance Holding Torque: Estimated at 0.4 N.m (approx. 56 oz-in). bj42d15 26v10 stepper motor datasheet exclusive
(Note: model number interpreted as "BJ42D15 26V10" — assumed to reference a bipolar stepper motor variant with 26 V rated voltage and 10 indicating either phase current, winding identifier, or series code. If you have a different exact part number or manufacturer, supply it for pin‑perfect specs. This post assumes reasonable industry conventions for similar motors.) : While some generic 42-34 motors are rated at 1
