Users have noted that the 23KM-C051-09V can reach temperatures up to 80°C under heavy load. To extend motor life, avoid sustained operation above 70°C. If you run the motor at 12 V or 24 V with a chopper driver, the actual heat generation will be determined by the average current rather than the supply voltage.

In the CNC world, this motor is a classic choice for driving the axes of desktop routers, plasma cutters, and laser engravers. Its 9.9 kg·cm holding torque provides the strength to move gantries and spindles accurately through dense materials like wood, plastics, and soft metals without losing position. As noted in technical discussions, it is often considered optimal for smaller-scale CNC machines with a working area of around 20x30 cm, particularly when paired with lead screws that have a 5mm pitch.
