Stepper Motor Datasheet | Bj42d15 26v10
(Note: Always verify with a digital multimeter. Continuity will exist between the pairs belonging to the same phase loop. Resistance between Phase A wires and Phase B wires should read as infinite/open circuit). 4. Driver Compatibility and Chopper Tuning
| Symptom | Datasheet Check | Solution | | :--- | :--- | :--- | | Motor gets hot (70°C+) | Rated Current = 1.0A | Measure driver current. Reduce Vref until current is 1.0A peak. | | Low torque / skipped steps | Holding Torque = 0.22 N·m | Verify you are using microstepping (1/16 or 1/8). Increase supply voltage to 24V. | | Motor won't turn | Phase Resistance = 2.6Ω | Check continuity. If > 10Ω, winding is burned open. Replace motor. | | Noisy, growling sound | Inductance ~ 4mH | Lower the driver decay mode (set to mixed decay). |
This technical guide compiles data across manufacturer specifications, community testing databases, and firmware repositories to present an accurate, actionable datasheet for engineers and makers. Core Technical Specifications
The most critical part of using the BJ42D15-26V10 is setting the correct current ( Vrefcap V sub ref end-sub ) on your stepper driver (e.g., A4988, TMC2208, TMC2209). Start with RMS . bj42d15 26v10 stepper motor datasheet
The BJ42D15-26V10 is designed around a hybrid stepper topology. It combines permanent magnets with a multi-toothed rotor to achieve high holding torque and precise stepping increments. NEMA 17 (42 mm x 42 mm faceplate). Configuration: Bipolar, 4-wire termination.
The BJ42D15-26V10 requires a dedicated constant-current (chopper) stepper driver. Do not connect this motor directly to a power supply. Compatible Drivers
You cannot use standard microstepping drivers designed for 2A/2Ohm motors directly with the BJ42D15 without modification. Here are your best options: (Note: Always verify with a digital multimeter

Stepper drivers are the interface between your controller (like a 3D printer mainboard) and the motor. The BJ42D15-26V10 is a low-current motor (1.0A) and is compatible with almost any standard driver. The TMC2209 is a popular choice for its "StealthChop2" technology, which makes the motor much quieter than legacy drivers.
BJ42D15-26V10 is an OEM NEMA 17 stepper motor manufactured by Hunan Keli Motor Co., Ltd. . It is primarily used in Creality 3D printers
To maximize torque at high step rates, your power supply voltage should ideally be equal to or greater than the motor's rated voltage. A paired with a current-limiting stepper driver will provide the best overall performance curve. Applications
