Engineering Reference Document Type: Simulated Datasheet Review Date: April 21, 2026

Based on manufacturer data and community measurements for the BJ42D15 series, the primary specifications are as follows: : 2-Phase Hybrid Stepper Step Angle : 1.8° (200 steps per revolution) Rated Current : 0.84A per phase Phase Resistance : Approximately 6.0 Holding Torque : 2.86 kg·cm (0.28 N·m) Frame Size : 42 x 42 x 34 mm (NEMA 17) Shaft Diameter Operating Voltage

The BJ42D15-26V10 adheres to the standard NEMA 17 form factor, making it easily drop-in replaceable in most automated systems. NEMA 17 (42 mm x 42 mm) Body Length: 34 mm (approximate, varies slightly by batch) bj42d15 26v10 stepper motor datasheet

sense resistor, you would tune the Vref potentiometer to approximately to supply a safe running current. Applications

1.8 degrees, meaning it takes 200 steps to complete a full 360° rotation. The BJ42D15-26V10 belongs to the 42mm (NEMA 17)

The BJ42D15-26V10 belongs to the 42mm (NEMA 17) frame size family, balancing compact dimensions with reliable holding torque. Electrical Attributes 12V – 24V DC (Typical operational range)

Most variations of this motor use a standard 6-pin JST-PH terminal embedded on the motor body, utilizing 4 active pins. Pin Number Wire Color (Typical) Motor Phase Phase A (+) Pin 4 Phase A (-) Pin 3 Phase B (+) Pin 6 Phase B (-) The "BJ" prefix designates a hybrid stepping motor,

The BJ42D15-26V10 is manufactured by KELI, a leading Chinese motor manufacturer specializing in micro and special motors. The "BJ" prefix designates a hybrid stepping motor, while "42D" refers to the frame size (42mm), which conforms to the NEMA 17 international standard (42×42mm mounting square). This standard ensures the motor is mechanically compatible with a vast ecosystem of brackets, pulleys, and lead screws. The "15" in the model number typically denotes a body length of approximately 34mm, while the suffix "26V10" likely indicates a specific winding variant with a rated current of 0.8A and a DC voltage rating of 26V. Designed as a 2-phase, bipolar stepper motor, it features a step angle of 1.8°, making it one of the most common types for precise positioning tasks.
