The motor has two phases (A and B). Each phase has a center tap (not used in bipolar mode). As a 4-wire bipolar motor, the center taps are not brought out.
The details a high-performance NEMA 23 hybrid stepper motor engineered by MinebeaMitsumi (formerly NMB Technologies) . This industrial-grade actuator is widely recognized for its robust holding torque, durable ball-bearing structure, and precision engineering. It serves as a primary mechanical driver in high-load automated machinery like CNC routers, laser cutters, 3D printers, and specialized banking equipment (such as automated teller machines and bill validators).
Defines the variant often tailored for mid-range torque applications. Physical Specifications Outer Diameter: Length: (typical motor body length, excluding shaft) Rotor Inertia: Detent Torque: Approximately Weight: 3. Wiring and Driver Setup 23km-c051-09v datasheet
High PWM switching can induce shaft voltages. The datasheet advises grounding the motor frame to the machine chassis using a star ground configuration. Do not rely on mounting screws alone—use a dedicated grounding wire.
Standard factory suffix often indicating specific output shaft styles (e.g., geared, D-cut) or connector types. Ersin Elektronik Common Applications & Compatibility CNC Routers & Mills: The motor has two phases (A and B)
Compare with similar NEMA 23 motors from Moons or Wantai to estimate.
Use continuity mode to find coil pairs. For bipolar series: two center-tapped wires left unconnected if 6-lead. The details a high-performance NEMA 23 hybrid stepper
The motor usually features two main connectors:
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
