The is a specialist component, not a commodity 3D printer motor. Its defining characteristics – 26V rated voltage and 26 Ohm phase resistance – make it uniquely suited for constant voltage drive systems and legacy equipment restoration.
What (Marlin, Klipper, Arduino GRBL) will control the steps?
Typically driven by 12V or 24V DC systems.

This careful cross-check is the most reliable method to ensure firmware compatibility and optimal performance.
Stepper motors do not have a fixed "operating voltage" in the same way a DC motor does; rather, they have a rated current. The "26V10" model is designed for a 26V DC bus; however, typical 3D printer motherboards (24V) or driver boards (e.g., TMC2208) can operate this motor effectively within a range of 12V to 36V, provided the current limit is correctly configured. Unlike brushed DC motors that must match voltage, this stepper uses a chopper driver to regulate current independently of the supply rail.
Because the motor has a low rated voltage (2.6V) and high current density (1.0A), Doing so will immediately burn out the internal coils. Recommended Drivers The is a specialist component, not a commodity
