Like all hybrid steppers, the torque of the BJ42D15-26V10 decreases as RPM increases. To maximize high-speed performance, it is recommended to use a higher input voltage to the driver (e.g., 12V or 24V), as this helps overcome the motor's back EMF.

Elara’s breath caught. She was a robotics engineer, not a physicist. But she knew that a stepper motor moved in discrete steps by energizing coils in sequence. If you drove it at exactly 26.10 kHz—not 26.1, not 26.11, but 26.10 —the magnetic field wouldn't just rotate. According to this schematic, it would fold.
