Brief: this product for sale is electronic spindle motors for cnc router. Model number is GDZ-100-3, power is 3.0kw, spindle diameter is 100mm, maximum speed is 24,000rpm. Cooling way is water or liquid. Water cooling is prior to air cooled spindles on cooling performance. Also, simply because this, water cooling spindle is ideal for both long time machining such as relief carving and short time machining like cutting jobs. It can keep working for 8 hours without stop if you change the water in time.

Common Sense Tip: the difference between water-cooled spindle motor and air-cooled spindle

1. Water cooling spindle is using of water circulation to cool the heat generated by the spindle rotating at high speed. The cooling effect will be good because the motor temperature (usually tested) will not exceed 40 degrees after the water has been circulated; the air cooling spindle is cooled by a fan from the top of spindle, and the cooling effect is definitely not as good as that of water cooling. Due to this point, water cooled spindle is more suitable to do the long time carving work than air-cooled spindle. But this is not mean that air cooled spindle cannot do carving jobs, it can do also, just its service life will get reduced after working for more than 4 hours continuously. For example, the carving jobs will take 6 hours to finish; machine with air cooled spindle have to work 4 hours first, then take a rest like 30 minutes, next start again to finish the carving. This way will have no harm on spindle. It will do harm to air cooled spindle to make it work for more than 4 hours continuously. While if same case to water cooled spindle, you can let it work for 6 hours without rest until finish the jobs. 

2. Noisy. The water-cooled spindle is essentially noiseless, but the air-cooled spindle is relatively noisy.  

3. Service life. If we did good maintenance on water cooled spindle like change water frequently or use industrial chiller for it, the service life of it will be much longer than air cooled spindle.
