![Conceptual diagram of NEMA 17 dimensions: 42mm width, 31mm bolt circle, 5mm D-shaft]

According to the official , here are the non-negotiable electrical limits. Exceeding these values will cause overheating and demagnetization.

: Pins 3 and 6 (middle pins on the 6-pin connector are often empty)

The table below summarizes the key electrical and mechanical specifications of the BJ42D15-26V10 motor based on available manufacturer datasheets and field data: bj42d15 26v10 stepper motor datasheet

This is a , where each of the two independent windings (Phase A and Phase B) is controlled by the driver to create the rotating magnetic field. In bipolar mode, each winding is bidirectional, allowing for higher torque output.

| Parameter | Value | | :--- | :--- | | | NEMA 17 (42mm x 42mm) | | Step Angle | 1.8° (200 steps/revolution) | | Phase | 2-phase bipolar | | Rated Voltage | 26V | | Rated Current | 0.8A - 1.5A (depending on variant, 26V10 variant rated for 0.8A) | | Holding Torque | ~0.2 - 0.4 N·m (28-57 oz·in) | | Inductance per Phase | 1.4 mH (typical, from Y1W01E variant datasheet) | | Resistance per Phase | 1.4 Ω (typical) | | Number of Leads | 4 | | Rotor Inertia | 35 g·cm² (typical) | | Body Length | 34mm |

Since I don't have the exact datasheet for the BJ42D15 26V10, let's consider an example with hypothetical specifications: In bipolar mode, each winding is bidirectional, allowing
