: Hybrid Bipolar or Unipolar configuration, supporting versatile driver designs. 23km-c051-09v datasheet
Lab automation and precise fluid pumping.
: 6-pin male terminal block layout on the motor body.
🔍 Pro tip: If the motor is unreadable, replace with a standard NEMA 23 stepper rated 9–12V and 0.5 A/phase. Adjust driver current loop accordingly. : Guiding repetitive pick-and-place arms or assembly belt

The 23KM-C051-09V has been successfully used in a wide range of projects: If you share with third parties, their policies apply
Optimized for mid-torque applications (often in the 0.8 to 1.5 N⋅m range, depending on driver voltage and current).
Because these parts are often sold as surplus or OEM components, the best way to get the exact wiring diagram is through these resources:
Rated for operation between -20°C and +50°C, the motor can be used in unheated workshops, outdoor enclosures, or cold storage facilities without special heating or cooling measures.
Designed to deliver significant holding power in a compact package.
