23km-c051-09v Datasheet

If the motor operates in an enclosure above 40°C, de-rate the current to 4.3A per phase to prevent demagnetization of the rare-earth permanent magnets.

(Invoking related search suggestions.)

The 23km-c051-09v is a bipolar, 4-wire, or 6-wire hybrid stepper motor (depending on the specific revision found in the datasheet). 23km-c051-09v datasheet

Data rates, modulation, and protocols

Commonly Blue/Red for Phase A, Green/Black for Phase B (with center taps, if using unipolar). Driver Recommendation: A chopper driver capable of If the motor operates in an enclosure above

If is a real component you have physically:

Designed to deliver significant holding power in a compact package. Driver Recommendation: A chopper driver capable of If

A: Measure phase resistance. Should be ~17.6 ohms (0.51A version) or ~1.76 ohms (5.1A version). 9V ÷ 0.51A = 17.6 ohms.

The motor features an insulation resistance of at least 100 MΩ at 500 VDC and passes a dielectric strength test of 500 VAC for one minute. This level of isolation ensures safe operation in typical industrial environments and provides a good safety margin against transient overvoltages.

The 23KM-C051-09V's popularity in the DIY and prosumer CNC space is not accidental. Its design makes it a true "workhorse," offering a compelling mix of performance attributes that justify its widespread use.

While specific proprietary datasheets are often restricted to distributor portals, I have compiled a comprehensive technical report based on the standard specifications for this series of motors.
