Bj42d15 26v10 Stepper Motor Datasheet

If you are currently troubleshooting or designing a system with this motor, I can help you optimize its performance. Let me know:

VREF=Irun×1.414=0.672×1.414≈0.95VVREF equals cap I sub run end-sub cross 1.414 equals 0.672 cross 1.414 is approximately equal to 0.95 V

Compare it to (e.g., in terms of torque). bj42d15 26v10 stepper motor datasheet

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

If you measure 1.8 Ohms, you have received a standard 3D printer motor – DO NOT use it with 26V. If you are currently troubleshooting or designing a

The "26V10" suffix on the model number indicates that this motor is rated for . An earlier table provided by ELEGOO explicitly identifies the BJ42D15-26VXX as an 0.8A motor. Furthermore, in an official Creality support document for the Ender 3 series, the "26V10" motor’s rated current is listed as 1.5A , and the recommended Vref for the TMC2208 driver is 1.06V. This difference is because 0.8A refers to the phase RMS current at the motor’s base-rated voltage, whereas 1.5A is the peak current limit required for microstepping drivers to deliver full torque. For safe operation, always set the driver’s current limit using the latter value.
