Do not substitute with a motor rated for 2.5A. It will not produce sufficient torque and may stall.
Unipolar (6-lead) or Bipolar (4-lead) depending on the specific sub-wiring configuration. Shaft Diameter: Typically 6.35mm (1/4 inch) 🛠️ Performance Features
A: No. The 23KM series are hybrid steppers. If you see encoder ports on the back, it might be a closed-loop stepper – still not a true AC servo. 23km-c051-09v datasheet
Based on the official Minebea Standard Hybrid Stepper Motor specifications, the baseline electrical and mechanical characteristics for the 23KM-C051-09V variant include: Go to product viewer dialog for this item. IDUINO NEMA23 18.9 kg-cm Hybrid Stepper Motor
Often, sites like AllDataSheet or DatasheetCatalog host PDF mirrors of these specific Minebea part numbers. Do not substitute with a motor rated for 2
The motor maintains >80% of its holding torque up to 5 revolutions per second when driven by a 36V, 5.1A chopper drive. Below 9V (direct drive), torque drops off rapidly above 300 RPM.
Minebea-Matsushita uses structured alphanumeric codes for their hybrid stepper series. Understanding how to read these codes clarifies the hardware differences between similar parts: Series Prefix Frame Dimensions Rotor/Stator Core Code Electrical Winding Variant Special Manufacturing Suffix NEMA 23 Frame Size C051 (Core length & stack) 09V (Specific internal resistance/voltage profile) Shaft Diameter: Typically 6
The motor works well with a range of standard stepper drivers:
