Bj42d15 26v10 Stepper Motor Datasheet May 2026

The BJ42D15-26V10 is a NEMA 17 stepper motor commonly found in Creality 3D printers, such as the Ender 3 series. While specific manufacturer-direct datasheets for the "V10" variant are rare, community data and specifications for very similar "V" models (like the V09 and V50) clarify its core performance characteristics. Core Specifications Model: BJ42D15-26V10 Frame Size: NEMA 17 (42 x 42 mm) Motor Height: 34 mm (standard "42-34" class) Step Angle: 1.8° (200 steps per revolution) Rated Current: ~0.84 A per phase

Based on its design as a "42-34" series motor, the following technical profile applies: Step Angle : 1.8° (200 steps per revolution). Rated Current : 0.84A per phase. Phase Resistance Holding Torque : 0.4 N.m (approx. 2.86 kg.cm). Nominal Voltage bj42d15 26v10 stepper motor datasheet

• Temperature Rise: Under full load, the case temperature stabilizes around 60°C – 70°C in a 25°C ambient environment.
• Power Dissipation: P = I² × R = (1.0)² × 26 = 26 Watts per phase static.
• Cooling: Passive cooling (aluminum chassis mount) is sufficient. No forced air required.
