Bj42d15 26v10 Stepper Motor Datasheet Exclusive 2021 «Free Access»

: Typically 0.84 A per phase. Some sources note it may be tuned as low as 0.8 A depending on the specific printer application. Holding Torque : Approximately 0.4 N·m (or 2.86 kg·cm). Input Voltage : Rated for a maximum of 24V DC .

💡 To prevent overheating, ensure your stepper driver's Vref is tuned to deliver no more than 1.5A. For high-speed applications, use a 24V power supply to overcome back-EMF.

If you want, I can: (a) format this into a printable PDF-style datasheet, (b) generate a wiring diagram for a bipolar 4-wire connection with a chopper driver, or (c) draft lab test procedures with detailed instruments and pass/fail criteria — tell me which. : Typically 0

The is a specialist tool, not a generalist. It sacrifices holding torque for speed, efficiency, and thermal management. Its exclusive 26V/10Ω winding makes it a rare gem for battery-operated devices, high-speed light-load positioning, and low-heat environments.

BJ42D15-26V10 is a NEMA 17 stepper motor manufactured by Keli Motor Group Input Voltage : Rated for a maximum of 24V DC

This exclusive datasheet synthesis is based on direct measurements, OEM cross-references, and application testing. Always refer to the original manufacturer’s datasheet for final design validation.

The high resistance (26Ω) relative to typical NEMA 17 motors (which often sit at 2-10Ω) means this motor is designed for constant voltage drivers rather than chopper-drive current-control. Driving it at exactly 26V DC will yield smooth microstepping without current spikes.

The BJ42D15 26V10 stepper motor is suitable for a variety of applications, including:
