Bj42d15 26v10 Stepper Motor Datasheet Jun 2026

: This is usually given in Amps per phase. For example, if it's 1A/phase, you would need to ensure your driver can supply this current.

Used in pick-and-place machines and automated lab equipment.

While official standalone PDF documentation can be notoriously difficult to find for specific OEM batch numbers, community testing, manufacturer correspondence, and cross-references from the Keli Motor Group establish the standard datasheet metrics for the BJ42D15-26V10 variant: Specification Profile NEMA 17 (42 mm × 42 mm) Body Length 34 mm (Often referred to as a "42-34" motor) Step Angle 1.8° (±5% accuracy per full step) Steps Per Revolution Phase / Configuration 2-Phase Hybrid / Bipolar Rated Voltage Maximum 24V – 26V DC Rated Current (Peak) 0.84A – 1.0A max Holding Torque ~2.86 kg·cm (0.28 N·m / 40 oz-in) Shaft Diameter & Style 5mm "D-Shape" or Round (varies by production lot) Insulation Class Class B (Safe operating temperature up to 80°C rise) Understanding the Part Number (Decoded)

If configuring via firmware (such as Klipper or Marlin using UART/SPI mode), you can input the RMS target value ( run_current: 0.65 ) directly into your configuration files. Pinout and Wiring Blueprint BJ42D15-26V10 bj42d15 26v10 stepper motor datasheet
