Unipolar (6-lead) or Bipolar (4-lead) depending on the specific sub-wiring configuration. Shaft Diameter: Typically 6.35mm (1/4 inch) 🛠️ Performance Features
: Uses all 6 pins. This setup accesses the center-tap of both phase windings, allowing basic control circuits to alter magnetic directions without complex H-bridges.
This is standard practice with modern chopper-drive controllers, which regulate the current to the motor. The higher voltage overcomes the winding inductance faster, allowing current to flow more quickly and improving torque at higher speeds. The driver ensures the motor never receives more than its rated 2.0A. 23km-c051-09v datasheet

The motor is equipped with , making it a versatile unipolar or bipolar stepper motor. The 6-wire configuration provides options for how the motor is connected. In unipolar mode, only four of the six leads are used, and a center tap on each winding is left unconnected, which simplifies the driver circuit but typically delivers only about 70% of the motor's holding torque. Conversely, wiring it as a bipolar series motor uses all six wires, or more commonly, the two center taps are cut and isolated, and the four remaining wires are connected to an H-bridge driver. This configuration allows the motor to achieve its full rated torque of 980 mNm but requires a more complex driver. | Parameter | Value | | :--- | :--- | | Frame Size | 56

The "09V" suffix often designates an OEM-specific winding. Similar models in this series (like the 07V) operate at approximately 2.0A per phase Precision Step Motors - Free
The is a high-torque NEMA 23 hybrid stepper motor manufactured by NMB (MinebeaMitsumi) . It is widely used in CNC routers, 3D printers, and industrial automation due to its reliability and precision. ⚡ Technical Specifications
Because the 23KM-C051-09V is heavily tied to custom commercial hardware, buying direct factory replacements requires finding niche electronics distributors or industrial surplus stores on eBay . If you must substitute this motor with a standard generic NEMA 23 stepper motor, match the 1.8-degree step profile, physical 1/4-inch shaft diameter, and confirm that your external stepper driver limits current properly to avoid overheating the replacement.
